Anyone have any tips in finding open atheists in the Bible Belt?

I'm at a point where I tell myself "fuck it,Life is too short, Imma compromise and date any muslimah or christian chick that I find attractive and deal with any religious bullshit that comes later". The only problem is that what if you guys decide to settle down, how are you going to handle with raising children concerning beliefs?
I mean, for me looking for an open atheist or an ex-muslimah can be a time-wasting effort,bit restrictive if you ask me and the experience of dating one could also be overrated,not that I have anything against y'all my forum sisters,I like y'all

but you may get the notion that you guys have something in common just because you're both ex-muslims or atheists yet later on when you start to know each other more, you will find out you don't actually have anything in common but beliefs which can be a real bummer.... Well, they are some that I share varying similar interests with(and even complete similar interest) but for someone that is based at sub-saharan Africa, I can't really stress myself on that.
