It's always been there.
In elementary school they did a school prayer over the pa system while we stood with our eyes closed and our heads bowed, in public school.
I was pretty dubious about religion in the Navy and made the mistake of saying something, which prompted a series of uncomfortable conflicts where roving bands of Christians attempted to gang save me.
When my drill instructor in boot camp asked what religion I was I said atheist which let to a two hour lecture delivered with a kind of weird insanity about how one day I'd call on God and after ignoring him to long he'd ignore me. There were a lot of cuss words as well. I find it odd that we have officers aboard ship called Chaplains.
It's in so many inappropriate places.
It's ignorance porn.

my brother in law is and My father in law was a young earther. My uncle was a klansman. I handled all three the same way. Avoid talking about those things that you know you don't agree with, and don't argue about their position, you can't change their mind.

Mostly in the UK it is only the very old who cling to such beliefs, you get used to finding ways of evading such questions, because it is hard to burn an old persons walking stick. But generally they know you don't agree anyway, and avoid it themselves, evangelizing has never really been socially acceptable here.

This is what eyebrows are for.

When I was young I just nodded and kept my mouth shut. I looked for areas we could agree on without having to tell a bald faced lie.

No one has a right to require you to affirm their beliefs. So if it is presented as a requirement for employment, you have every moral justification for telling them whatever they need to hear. Conversely, you have every practical reason for seeking employment elsewhere.

In friendships or family relationships there may be a different dynamic. Some relationships may be more valuable than “being right.” If someone feels a strong need to have their beliefs validated, a loving response would not likely include kicking the crutches out from under a cripple. And whichever person has the greater need to have their beliefs affirmed is the one who is more crippled.

What I have usually done in the past is try to assess how important it really is to preserve the relationship, and then share only as much of my views as I think the situation can bear.

Relationships are not static. They can grow over time. The greater the relational investment, the more truth they can bear. It doesn’t all have to be concluded at Thanksgiving dinner.

There were times in my own life when I believed things that now seem absurd. I’m glad there were people in my life who stood by me while I grew at my own pace, and didn’t feel a need to “set me straight” at every turn.

It is never okay to affirm someone else's false beliefs. You are doing he person and all others involved no favor in falsely affirming untrue beliefs.

Look into the legality of employers actions! Call the ACLU or your area's hotline on employee rights. That is a far cry from simply being stupid!

I've only encountered it once when someone wanted me to join the Masons. I declined on being told that I had to state that I believed in a higher entity. It was suggested that I pretend. I still declined.

No. Don't encourage them.

My hiking partner Karen is vegan. At first, she lectured me on the superiority of her diet.

"Hmm....interesting... uh, huh...." I murmured, hoping she would wear down.

"Karen, I want to enjoy the serenity of the mountains, to be here now," I said firmly when she ranted about horrific factory farming. "Please stop talking about that."

Eventually, Karen got the message. She praises me for my "generally healthy diet."

For Karen's dog, I bring meat on hikes. It amuses me. Yesterday Bonnie got roast turkey chunks for lunch. Karen appreciates it. Bonnie never gets meat from Karen.

However, Karen buys dog food with a high percentage of meat instead of filler.

I would affirm only their right to their opinion. I would not affirm something I feel is untrue.

My sister demanded that I not fact check her. She was posting political nonsense, and I didn't want people to be swayed by her falsehoods. So, I stopped fact checking her. In fact, I stopped talking to her at all (and not because she demanded I not fact check).

I have nothing in common with people who believe that stuff. I can't imagine discussing religion with anybody, I'm not interested in that subject. I have no desire to change anyone's mind, they won't change mine. They don't want to hear what l have to say and I don't care about their beliefs. I'm not or less apathetic.

#1, they cannot fire you for having a different belief than they do. If they attempt to, I suggest you call the ACLU immediately. I'd never support this. It sure would make me cut that person off in a hurry. I don't miss it or them.

In One ear out the other!!!

I wouldn't do that for anyone.

I have experienced proselytizing during moments I thought were inappropriate for a corrective response. In those instances I simply stated I had different views which I would be happy to discuss later. But when it happens in the right circumstances I don't hesitate to explain my Agnosticism.

No. Facts are facts.

It's never okay to support ignorance. However, when it's your work... silence is sometimes the better option.

Whenever any kind of religion or woo has come up at work, whether it's a coworker or boss, I say, "My momma taught me I was not to discuss religion or politics at work. You wouldn't ask me to go against my momma, now would you?" And that would be the end of the discussion.

There's no point in arguing with them but affirmation can be avoided.

No, it’s not, however if your life depended on it, lie through your nose like there are no tomorrows

Explaining climate change and species extinctions to a theist.

"Okay so God told Noah to save all the animals. correct?"
"Yes...?"
"So whether or not you take the story literally or inspirationally. There is an implicate duty placed upon mankind to look after that which God has given us dominion over, correct?"
"Yes"
"Is there any later part in the bible where God has overridden this duty or said "It does not matter now","
"No"
"So we have a spiritual as well as a secular duty to stop killing the planet and destroying whole species at a genocidal level, correct?"

I don't tolerate ignorance because of religion. I just don't. Religion has been proven wrong so many times at this point its willful stupidity to believe what it says against science.

I'd seriously suggest not reinforcing delusional thinking. Also suggest politeness, but you don't do someone like that any favors by accepting their lunacy as anything other than what it is.

Affirming other's false beliefs IMO is disrespecting yourself.

"Only 6,000 years old? Where is your falsifiable evidence to support that claim?"

"You are perfectly free to believe that the young Earth hypothesis is true. However, I reject that hypothesis because of the lack of supporting evidence."

"If you require me to affirm your belief as a requirement of working for you, then I cannot regard you as being a fit and proper person to be my employer."

I have never told any such untruth because I will not tolerate being bullied.

I make no apology for attacking the core of somebody's belief system when it is manifestly ridiculous.
