Ok, but you selectively quoted a part that makes it sound like Popper is fine not tolerating any intolerance. He wasn’t. He basically said you tolerate intolerance as much as you can without risking the collapse of social order.

Big difference.

I copied and pasted the entirety of the top section of Wikipedia with no editing. That section says "if a society is tolerant without limit" (my emphasis) which goes to your point that there is a threshold here.
