People who don't like wrongthink keep saying that line. Then they call others Nazis and fascist.

Really, their statement is just a slightly watered down version of

"There is freedom of speech. But I cannot guarantee freedom after speech."

This guy, btw, was known as the Butcher of Uganda.

As for cancel culture, I'd hate to be an employer who is spineless enough to fire an employee over shit he said on the internet. What matters to me is his performance. Now I don't know how things work in America but in my country employer has to have a valid reason to terminate an employee. I don't think judges would be too happy to hear that you fired an employee over something as insignificant as an opinion on the internet.
