You can die by not having a blood transfusion. You can't die by not having sex, yet you argue that thinking certain kinds of sex is wrong is hateful but thinking someone should have died is not?

I believe most Christians believe being attracted to members of the same sex is not sinful, it's the sex itself that is. Sex is not a fundamental aspect of who people are.

For what its worth I don't think either beliefs are hateful, as long as it's your own belief and you don't act hatefully because of your belief. It's the actions motivated by hate using a belief as a defense that are wrong, not the belief itself. If I think the Bible says homosexuality is wrong, but I also believe others should be able to come to that belief on their own and it's not my place to impose that especially on non Christians who would have no reason to follow the same rules I do, how is that hateful? If I think reading books is wrong and I think people who read books would be better off if they didn't, but I'm not going around doing hateful things to book readers or attacking them verbally or physically, is it still a hateful opinion?
