Earlier quoted context omitted.
Why on earth would you support arresting people for any speech, hate or otherwise? It is just so obviously a terrible idea that has been regurgitated over and over for thousands of years, countless books, wars, philosophical treatise and here we are. No wonder we aren't going to make it.
Can you define a clear line between free speech and call for murder? https://en.wikipedia.org/wiki/Will_no_one_rid_me_of_this_tur... I am very much pro free speech, but I do draw the line with implicit or explicit threats of violence. And this line is debatable, sure, but saying any words are just free speech? To escalate the example, Hitler giving the order to exterminate the jews was just free speech?
My real point here is that this discussion specifically has been so thoroughly debated by brilliant people that I have trouble understanding why this hasn't been simply closed as proven like we do in math. Eventually you reach a level of argument where there is simply nothing left. We have reached it. Curtailing speech and thought simply never works as intended and always brings greater harms than the alternative.
