and it required some eggshell walking.

i make sure to check before i leave/kick them out the next morning

To answer your question, usually prior to the flirtation. I usually don't flirt with someone without having an already established rapport on subjects of interest and as an introvert, not often. Lol ! I usually find myself attracted to gragarious personalities so I usually know more about them than they do of me. So I am able to filter the undesirable fundamentalist out pretty easily.

uh ...when, or if someone asks me directly, which doesn't happen often

I've never had to do that. I guess I don't really attract religous people and as soon as I hear the word Jesus or church, I immediately lose interest.

Which do I reveal first? I'm an Atheist, Vegan, Democrat with Socialist tendencies.

Never really thought about it. The kind of women I am attracted to are uncommonly bright, so I essentially never encounter dogmatic beliefs (religious or otherwise) and they are typically at least not religious if not agnostic.

I guess that would require meeting people or god forbid date. Don't think I remember what that is. ?

First time we meet if they're interesting enough.

If I use online sites, I state it clearly.
In Colorado I never had to, but here (rural VA) I am an anomaly.

Why not before you even start . . . . otherwise it is really just game playing.
