I know the instinctive response to (hopefully) most people here would be "YES", but gay marriage is not the only secular issue that churches fight tooth and nail. I recently read an article in Time (it's also on their site, but requires subscription) about how ever since Roe v. Wade, abortion has been losing battle after battle. And when we get down to it, abortion, just like gay marriage - and I guess the death sentence too, though I would hesitate to put it in that group - are cases that secular and religious views differ drastically on.
Gay marriage is the most clear cut of all of course - legally it could ONLY benefit society and it hurts no one. But abortion is just as clear cut if we take religion out of it - with the proper time-frames given, biologically speaking it is simply NOT murder. I remember Kulindahr making a great argument about the different approaches to the subject, I hope he could find and repost it.
So, what do you think? Are there cases where religious consideration SHOULD be allowed to influence secular decisions, or should the separation of church and state be absolute in all matters?
Btw, feel free to add other fields. Gay marriage and abortion were just the first that came to mind.
