You could argue that they're not actually talking about the Paradox of Tolerance. (See philwelch's comment for what the real Paradox of Tolerance is, according to Popper.) You could even argue that they're not actually talking about the Paradox of Tolerance as defined by themselves. But at that point, the Paradox of Tolerance becomes useless, because whether it's being applied correctly or wrongly depends on the honesty and correct judgment of the one applying it. And it's really tempting to use it without honesty or correct judgment, all the while claiming that your side is the good guys.
