I don't profess to be familiar enough with the bible to state conclusively 'the Bible says this' or 'the Bible approves of that'. But see the earlier posts about the condoning of slavery. Maybe the Bible isn't the be-all and end-all moral guide.

Anyway, I'm not about to dictate to Christians what their religion is and isn't compatible with. They know their own religion better than me. What I will say is that I won't always agree with them, and if they're going to have some views that I find offensive or discriminatory, then we should all work to change those views.
