It would be like saying "a peaceful person would never punch someone in the nose". But what if you needed to punch someone in the nose because they were trying to kill you for no reason? That doesn't mean peaceful people don't exist, or that peaceful people need to let random people murder them. It just means that the determination of peacefulness is contextual.
it would be like saying, as the sibling comment did "a peaceful person would never punch someone in the nose" ... except that a society that aims for peace, and is beset with violent people, is going to have to quell that violence. This might involve reserving the right to punch the punchers.
Restrictions on free speech are much more dangerous than any hate speech. You won't get a new Hitler by blocking speech you don't like. It's the opposite: new Hitler will start with blocking free speech. That's what every authoritarian regime does first.
Just because someone wrote in length that white is black, white does not become black. Likewise, intolerance does not become tolerance.
You do not tolerate something => you are not tolerant.
You oppose free speech only for really horrible people => you oppose free speech.
It's really binary, and wherever Popper wrote, it does not change this simple truth. But, of course, you can hypocritically pretend that it does.
But if you start framing things as "defending peace (by force)", you may quite possibly have your arguments taken over by the people attacking whatever you want to defend. Because they can use the argument just as well as you.
People say it like it's a damnation of the idea. Things in life are fuzzy, that's why it's literally called a paradox.
The most tolerant people in the world are not going to be ok with a 20 year-old having a sexual relationship with their 12 year old daughter because of the danger involved. That's the paradox of intolerance, that everyone has a limit, and if you have no limit, someone else will pick it for you and cause damage on their terms.
We don't generally tolerate violence in the west. Yes, it's an intolerance, but it's for the greater stability of society.
but I have absolutely seen people use the paradox of tolerance to argue for some shitty opinions, so it must still be dealt with care. You can imagine a KKK member using it to defend their choice of not allowing blacks to be free of lynching.
Hypocrisy: The practice of professing beliefs, feelings, or virtues that one does not hold or possess; falseness. [0]
Paradox: A statement that seems to contradict itself but may nonetheless be true. [1]
Every time I see someone here mentioning someone the paradox of tolerance, it is to support restriction of speech for someone else. (someone really bad, of course - fascist, antivaxer, racist, you name it), and these people always hypocritically consider that they support free speech, just not for those bad people.
