No one chose or can help being gay. He's sending people to hell based on something they can't help. That's not very good. Either it isn't a sin or he created gay people this way.
Homosexuality isn’t some special, exotic temptation that works differently. You didn’t choose to feel attracted to the same sex, but you can choose to resist those thoughts and not act on them.
More importantly, we’re all sinful by nature. But God didn’t make us that way. The whole point of Christianity is that, yes, we are all sinners, people who have been corrupted and deserve damnation, and no matter how hard we try to be good, we will fail, and this is exactly why we needed someone else to intervene for us. I need Jesus, you need Jesus, everyone does.
