About 5 years ago it would have a been a definitive no, but back then I was going through my staunch atheist, anti-religious phase - "Richard Dawkins 4 pope" hats etc. I believe almost all atheists go through that at some point. I grew out of it, some don't, whatever.
My philosophy on this subject (always subject to change) is as follows:
I can only judge someone based on their actions, not their mode of thinking, because I can never really know what someone is thinking.
I also cannot judge people on the things they say because talk and all human-human communication is not a crystal clear window into the mind. People do not and never have used words to truly express what lies beneath the surface. They insinuate, manipulate, create this picture of themselves to others as they would like to be seen, be it to elicit sympathy, attraction, respect et al.
Just scanning the threads I've participated in over the last few days, people love moaning about their love lives. Some blame everything on the people around them, taking no responsibility for themselves. Some blame their own failings entirely. Some take a middle road. It's all talk though, how many of them do you think are going to make a sincere effort to change? In 6 months how many of the same names are going to be popping up in the same discussions over and over and over? Without action to back them up words mean precisely f**k all.
Now religion has an effect on the way people think, but not to the extent some atheists like to believe. Most non-instinctual human behaviour is learned from and kept in check by people around them, i.e. we are herd creatures. Religion fills the holes when they feel hopeless, or is used to justify something that they can't quite rationalise to themselves. Sometimes it provides an answer when they don't understand or when they don't want to understand the other explanations offered. Take a look across the pond, you will never see so much hypocrisy in one country. I'm willing to bet you can count the number of Christian Americans who have given away all their money and material possessions and wandered the earth, itinerant, spreading the teachings of Jesus on one hand.
Let's say I find a nice girl who spends her free time helping local war orphans (a lot of those in England hehehe). Does she do that because she feels the same empathy for those orphans that most non-sociopathic humans feel? That would be great.
What is she is devoutly religious? Does that instantly invalidate her actions, not at all. She may well call that yearning to help "a message from God" but she is still the one driven and choosing to act.
Worst case (and unlikely) scenario, she feels nothing for the orphans and helps them out of fear/greed based on things she has been taught about the afterlife. Although that kind of thinking is wrongfully attributed to all theists sometimes, it's rarely the case. Sociopaths or the extremely selfish like that tend not to be kept in check with religious beliefs, as is seen everywhere they are more likely to twist the religion to justify themselves (or create their own).
What I came to realise is that all humans are filled to the brim (even myself) with nonsensical thoughts and as such there is no "doing the right thing for the wrong reasons" - so she is still of higher value to me than some liberal feminist wank-philosopher spouting her opinions on the internet all the while doing nothing of any real value to anyone.
In conclusion I judge would-be partners on actions (or lack thereof) alone, not talk or self identified religion. I would consider dating the most insane religious zealot if I approved of her actions.
