I wonder how someone like Hitler would have been treated. I guess free speech advocates would have helped him to spread his sick ideas and rise to power? Free speech needs to have limits somewhere. If others are insulted, smeared, de-humanized, if hate is spreaded, if under the protection of free speech people rise to power who poison the political climate, then the whole system is in danger of falling apart, with all the good elements, even the right for free speech.
