...Spreading all kinds of vicious misinformation and disinformation about gay people and homosexuality isn't a very "Christian " thing to do as far as I'm concerned.
If a Christian :straight: believes that an individual will go to hell for his sin, is he wrong to warn him? 1 Co 6:9-10
If I say to the wicked person, ‘You will surely die,’ but you do not warn him—you don’t speak out to warn him about his wicked way in order to save his life—that wicked person will die for his iniquity. Yet I will hold you responsible for his blood. But if you warn a wicked person and he does not turn from his wickedness or his wicked way, he will die for his iniquity, but you will have saved your life (Eze 3:17–20).
