> most of us, even those who love free expression, would not be comfortable with giving space to certain assertions even in places that are meant for intellectual contention I think that's the problem. Any condition beyond being not insulting and not threatening leaves a place to drive in a wedge by those opposed to free speech. They say, if you won't let this Nazi speak, you shouldn't let this person I associate with Nazi-ism speak. Instead we should let the Nazi speak. And the pedophile, human extinction advocate, anti-vaxxer, etc. We don't have to listen, but neither should we punch them, rhetorically or otherwise, as long as they follow some minimal content neutral standard of decorum.
