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.
Like more or less anything real, this is not a simple binary problem.
That's Popper.
Does that sound like "we can't let people speak"?
Or would that actually be more in the lines of "we should expose their followers to the arguments their leaders don't want them to see"?
Some of people here who take free speech for granted do not know its value. I live in a very authoritarian country, that once had free speech, and I have seen how restrictions on it creep in. And what I see happen in US and Europe follows a far too familiar path.
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.
Also, do not equate actions and speech - and we're mostly arguing about free speech here, right?
Furthermore, such black and white thinking is often a sign of mental illness.
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.
