I mentioned it before, but it's a lose-lose situation if he wants to "debate" you. You either deny because you know he'll just make sex jokes instead of actual arguments, and he acts like that means he won. Or you go on his stream, chat tells him what to say (sex jokes), you get kicked as soon as you say something that mildly discomforts him, and then he acts like that means he won. The only winning move is to block him. Lucas will still act like he won, but you at least don't have to see it.
