sexually preying on children does justify murder IMO
That’s entirely different. That is not what he was talking about. He said that God commands me personally to go out and murder every homosexual I encounter. He said that God commands all of us to do that, including you. Then when I stood up to him, and pointed out the fact that god does not command us to commit mass murder, he accused me of being in the group of people he is commanded by God to murder.
Now, without hiding behind nuances, or changing the subject, do you agree with him that God commands you to murder homosexuals? If you don’t agree with that, quit pretending you do. If you do agree with it, have the courage to say so, without the cowardly head games.
