Man, as an agnostic myself, the next girl I date has to be agnostic. It's not any kind of a problem for me to be friends with people of any religion as long as they aren't intolerant. If they're tolerant I'm happy to afford them the same respect. But, I know I'm not dating with the purpose of getting married or having kids or anything just yet, I'm still far too young for that, but just on the slim chance that I do end up with someone I date now I want to be able to rest assured that my kids won't be brought up in a smothering religious environment. I'm not by any means going to go out of my way to even promote agnosticism to them, I just want to bring them up in a secular environment where whatever decision regarding religion they make won't have any negative consequences. That's something really important to me.
