Paul Hart doesn't have the right, he has the freedom to do so. Try not to confuse the two. No one has the right to track down and beat up anyone. No one has the right to beat up anyone outright. There has to be sound justification for it.
He will not be free from consequences for being affiliated or supporting racist, Nazi, hateful shit, however. Whether he spouts off the views aligned with that ideology or not, he sure doesn't mind being supported by or supporting those that do...
It was nice half forgetting about Paul until this thread reminded me of his sad MAGA delusion deepdive. Ah well.
