The article cites a case of online harassment from right wingers towards an immigration friendly politician that was ultimately shot. Are you seriously using this in defense of “but muh free speech?!”

“No, you have free speech as well, but it is also has its limits.”

Which is true. A lot of Europe learnt from World War II that certain types of speech should not be tolerated. In the rest of the article there are examples given - neo-Nazis for one. I am not particularly keen on tolerating the freedom of speech of Nazis or others that call for genocide and killing.
