Almighty God hates not people but sin!
Has always been justification for prejudice, bigotry and hate, while denying that it's really that. Or you wouldn't need to say it. It's also part of an authoritarian ideology that assumes that it's possible for everyone to fit into an idealistic mold. Those who are discovered not to be, must be blamed and you claim that it's not your problem, but theirs. To justify their rejection or oppression. Ironically, in such a hypocritical setting, you pretend to be morally superior and hide who you really are to the elitist cult. And are tormented with guilt. Until you know better, then you'll be the next to face rejection. You'll denounce the ideology and they'll claim that you're promoting hate against them. And that they can't hate you, only your sins. While demonizing you. Just like you, they'll also conveniently redefine whatever "sin" may be. For instance, lying to libel someone or a group is supposedly no longer a sin. Hate is supposedly not evil, but "out of love", etc. It's never "God" who hates, it's always hateful humans.
Finally, this is politics and war accelerationism, manipulating with religious rhetoric. Hoping to install an oppressive theocratic regime that would oppress, including most Christians who wouldn't agree with its abuses.
