Well, it's not black or white. There are opinions that I don't agree with that I think are still completely legitimate and perfectly moral. There are opinions that I take serious issue with and may even find immoral but for which I'd still claim that it's worse to try to suppress them than to allow them. And then there's stuff like incitement to violence or the president of the USA spreading dangerous lies about an election ... tolerance can only go so far. Of course, it's a difficult call to make. Of course, no matter what you decide, someone is going to be angry. But you can't just not decide, you do have to take a stand and by refusing to do so, you have effectively already decided something (that's the whole point of Sartre's philosophy btw, which was inspired by WW2).
