This is where the fetishizing of free speech and debate goes bad. I get to deny your basic humanity and your right to exist, and you now need to convince me otherwise. I get to freely make assertions that don’t challenge my privileged status but do potentially do great harm to you, and I have no responsibility or obligation to others — others who may even consider those statements “wrong beyond doubt” — to make defensible statements, and the onus is entirely on you to address them, and if you don’t, you are an intolerant tribalist. Why do you get so angry when I merely want to deny your civil rights, or enslave you, or kill you? That’s not very logical.
