It's really not the womans fault entirely. They actually think that's what men want to see, even the"deep water" ones. That being said, for the most part you are correct, a chick with half her titty showing in church is probably not relationship worthy but she may be "relations" worthy
I have defended Christians many times here, but I do not go to church and would not consider myself "religious" really. I respect their beliefs etc.. but the massive hypocricy I see in churches makes me want to puke. I think I am better off on my own.
Disclaimer:
This does not mean I think all church goers are hypocrits, not in the slightest. I simply think the actual organizations are run more like businesses than they were ever intended to be. Many, not all, churches around here could pass as fashion/car shows, not good IMHO.
