The new testament does have some not nice things to say about same-sex relationships IIRC, but nothing that condemns it nearly as strongly as the old testament. Just "will not inherit the kingdom of god" or some junk like that (which applies as well to thieves, drunkards, idolators, and adulterers, which I am sure encompasses a number of "good Christians").

It's all just silly, honestly. If the whole point is that people will be judged for whatever in the afterlife, then why care what anyone does in this life as long as it doesn't affect you directly? If gay people don't want to be "saved", then leave them the fuck alone. Pretty sure the Bible says that salvation shouldn't be transactional anyways.
