But from his point of view he isn't wishing his hell on anyone, he genuinely doesn't want people to go there. It's the old analogy, if someone is about to walk into a fire you stop them. From his point of view, if he stays quiet, then people are walking into that fire, and to not warn them is unloving. That's the perspective he is coming from.
I disagree with Izzys hell and I think the theology has been messed up but I can understand or see it from his view to some degree. Does Izzy want gays to burn? If he did, then that's hate speech, does he want to save them from burning, then he's trying to help from his perspective.
