Lying about it is pretty much illegal. Also, I showed a source in this thread somewhere, and I'm pretty sure one exists in the topic post- If gays were allowed to donate blood, we'd have much more of it. I think in this case, lying about it(as long as you're clean) would be perfectly fine. If they don't go around prominently proclaiming their sexuality, no one is likely to figure it out. These are in no way the same. The fast kids in sports have skill; they worked for it, that's why they get that advantage. Marriage is a right, and everyone is morally entitled to the same rights. Christianity (or any other religion for that matter) does NOT own marriage. Seperating church and state is what should be done. Everywhere. A church doesn't want to marry a couple? Fine, so be it- But who are they to say they cannot marry at all?
