You can debate your point with out dehumanizing others, when you can't, you've already lost the argument.
No. You can’t. And giving a “open mic“ to the Nick Fuenteses and Stephen Millers, and Charlie Kirks of the world who will put on a suit and a tie and try to “debate” you while dehumanizing others with nice sounding words gives them a platform to spread their hate while framing it as a “civilized debate“ rather than the coded bigotry that it is, while you cast aside any responsibility for letting them do it, tossing your hands up and claiming “free speech”.
It’s plainly and obviously bullshit. It’s like inviting a vampire into the house and then being surprised when everyone turns up dead.
