"People listen and actually murder several million in your race/religion, get the fuck over it."
They took direct violent physical action which harmed millions. They were wrong and should be punished.
"Speech is an act. It's a more powerful act in terms of efficiency than any sticks or stones. It has consequences - sometimes these consequences should involve legal sanctions, and often not, but there are always ethical consequences."
Speech is a non-physical indirect exchange of ideas, that's it. Ethics is still about ideas. "Sticks and stones may break my bones but names will never hurt me." The minute someone takes physical action to harm someone else they are wrong. That's where consequences should be exacted, nowhere else. In order to have freedom of speech you can't have consequences otherwise speech won't be free as self-censoring will be the order of the day. Something we see a lot of anymore.
