I am not confused, thinking like, or being a Nazi is not a reason to accost, assault, or murder someone.
Otherwise, maybe I deem a Communist, a Liberal, a the bourgeoisie or anyone else's thoughts to be forbidden and call them "fucking Vegans!" and hit them with rocks.
Then, we will see who is next.
Maybe I think John Oliver is an atrocious Commie-Nazi and will have him hung.
Why not? What thoughts are we outlawing? Are you the judge? Is history a good judge?
The Khmer Rouge? The Reign of Terror? The Cultural Revolution? The Night of the Long Knives?
No thanks.
We should feel privileged when living in or visiting a society that does not allow the persecution of people for their thoughts or ideas.
History? Tell me, what has history shown to be the only way to deal with Nazis?
