The marketplace of ideas is a nobel and ideal state. However, its weakness shows in a low trust culture - those like Kendi will exploit it to initially be heard then discard it once they’re in power.
Without strict controls over who is and isn’t allowed in our culture we’re left with a “at your feet or at your throat” predicament. Subversive individuals are death to a culture (the thing Popper was referring to in the paradox of tolerance - you have to draw the line at life or death, not simply because you disagree). Trust is everything.
Or to put it in different terms: democracy can AT BEST work somewhat ok in a homogenous high-IQ population. As soon as the constituency becomes multi-ethnic, people stop voting for "whats best" and start voting "which group is favoured". This is not a theory but a historical observation.
Popper was an idiot and his "Paradox Of Tolerance" can only lead to tolerance becoming the only permissible value and therefore decline, since tolerance is the absence of values. His university colleagues held him in such disregard that they threatened to quit unless he was cast out. Truly the patron saint of midwits and leftist.
