i think you should get too know them a little so you can show them just because you don't believe youre not a bad person

I tell them immediate. I'm too old for games. You have to be tactful and respectful though.

You might wanna hold off for a little bit and get to know each other first. Rejecting someone based on one trait isn't right.

I always say I am an Atheist. If the person gets all wrinkled up it means he/she has not brains and I run from brainless people

It should have been the second...or third thing you said to that person.

If you are hitting it off otherwise, maybe drop some hints that you aren't religious and see if they adjust their conversation, or double down on religious talk. I've met people who assume I'm religious, so they purposely insert a lot of god talk to impress me. After a few hints or outright blurting out my atheism, it's funny how some people can attempt to see my point of view and may be closet atheists themselves! Ya never know!

When the first girl I genuinely loved found out that I was a nonbeliever, she dumped me. I have never forgotten my feelings for her.

Not necessarily the very first time unless you feel like there's a connection but if you feel like the relationship is going anywhere I would definitely get any major issues discussed and out of the way before you allow yourself to develop deeper feelings

I would have it on my profile; a new prospect's being agnostic, or indifferent to their own religion, would be a stipulation for my accepting dates at all.

If you seem to have a lot in common, follow that path. Eventually, you will reach a moment in discussion where you will reveal some of your positions on religion and politics. The other person will also reveal their perspectives as well. Some people are more accepting than others. They will probably tell you whether they see this relationship developing further or not at that point. It's a gamble. But always be honest up front if asked.

I make certain they know up front. I want there to be NO misunderstandings. I also cannot see myself in a serious relationship with someone who is what I term to be "superstitious".

It wouldn’t be the opening gambit to the first conversation with someone you are meeting for the first time. If this is a possible romantic partner then I think quite early on in the relationship you should let them know your views on religion, if it is any other relationship, work or social, I don’t see any reason to mention your non belief at all.
