For example, a lot of Palestinians are not tolerant towards LGBT people -> a lot of LGBT people are not tolerant towards Israelis -> a lot of Israelis are not tolerant towards Palestinians.
Also how do you know if you are intolerant or intolerant towards intolerance?
You don't need to, it's all intolerance.
Nice bait with broad sweeping generalizations there.
One of critiques of "Paradox of Tolerance" is its proponents (probably not Karl Popper himself) take the argument to its extremes (similar to the generalization you posit), while the reality is more of a spectrum.
And pretending that there aren't large swaths of people who have different ideas and you can group them into "tolerant" and "none tolerant" is also a generalization.
“Fuck you, that person is intolerant, I get to do whatever I want to them. And man, how uncultured are you that you would even suggest otherwise. You must never have heard of this philosopher!”
