I've said many times before here, and some have admitted it, many people on this site are just mad at god/religion for however it let them down or hurt them. Consequently it's understandable that they might also hate people who believed as they used to...or it was believers that hurt them. Either way you get to block people you don't want to hear from but I think you should understand where some of them are coming from.

I do not hate religious people. I just feel that they have very flawed logic which tells me they are not credible. What is the problem here? They are unable to admit that they do not know something. The plan for everything is in their bible, but nobody knows the will of god. You must be holy and beg and plead with him.

I don’t think your perception is the reality. I’ve never witnessed hatred toward people on this site and I’m on it daily.
I’ve seen attacks on bad ideas, which is commendable.
I’ve seen and been subjected to prejudice by some left extremists, however. But that, in my view, is their ignorance, not actual hatred.
I think your response in the end, is what matters.

Welcome, I'll lift a pint cheers.

Welcome aboard!

Guilty as charged.

Are you not possibly confusing attacks on religion with attacks on followers of religion ?. There is a big difference.

Welcome to the asylum. Enjoy your stay.

I'm one of the members who have no use for theists.

I used to believe in the whole "live and let live" thing. I didn't care what anyone believed, as long as they didn't try to force anyone else to live the way they thought they should.
Unfortunately, that is no longer a viable option.

Far too many believers think they have the right to dictate the behavior of others.
Far too many more go along with that.

The influence of theists have on public policy is beyond the pale, and I can't abide it.
Too many believers have influenced public policy to the point where they are openly causing harm to those they feel are less-than themselves.

Their incessant and deliberate intrusions into the private lives of citizens is unacceptable. It has become such a problem that laws have had to be enacted to protect against their interference.

I find their beliefs and behavior worthy of ridicule and derision. I refuse to hide it.

If my responses to them are unpleasant to you or anyone else, block me.

Attempting to psychoanalyze anyone's animus in a public forum is a waste of time, and quite unlikely to produce satisfactory results.
If you really want to know why someone seems "hateful" towards theists, ask them directly.
Everyone has different reasons for feeling however they do.
There are no blanket explanations that would cover the question.

Welcome and feel free to block the idiots

Someone bothering or harassing you? Block them. Problem solved.

I really have almost no friends that are believers, and even with them, religion is a non-issue. It also almost never comes up in my very limited small talk with neighbors. So I really don't care about believers in general or what they think. Only when it gets into the level of government and society where they try to impose their religion on us. Then it matters to me, but I couldn't care less what they believe or do in their private lives.

I'm on agnostic.com. When I first joined this site in 2017 people were more accepting of religious people on here, while I was inactive for awhile the atmosphere changed drastically. People on here enjoy their safe space, get offended easily and block people with opposing views daily. I for one questioned my beliefs heavily when I first delved into atheist content on the internet. (Years ago when I was a believer) Some of the people on here probly would have pushed me further into religion rather than provoke my thoughts. I definitely see where you're coming from.

Some people need that outlet to not feel alone because they were surrounded by it for a long part of their life and still have trauma or mental anguish from living the way they were taught to do so long. I don't feel it's too hard to talk to these folks and help them through it or just ignore it.

Lol troubled backgrounds.

Even as an atheist, I can get along with all the major religions, except for Islam, which is actually a cruel, imperialist political ideology.
My opposition to the ideology does NOT imply hatred for Muslims, who are deceived, oppressed and enslaved by their indoctrination. They need to be helped and encouraged to apostatize, freeing themselves and humanity from the scourge of Islam.

A few of my friends are religious. I don't care
