I don’t mind seeing people free with their rhetoric. It lets me know who they really are, instead of who they pretend to be. In that way, political correctness has served to disguise folks we should avoid as in “a man convinced against his will is of the same opinion still.”
As to the “open season”, it surely is provocative these days though not quite as provocative in June as August but I recall the brouhaha a couple elections ago when Gabby Gifford was shot. They blamed the Republicans for an advertisement which included target symbols over politicians they wanted to defeat. The open season remark could be the same so I would be willing to dismiss that rhetoric but not the BLM and all Trump supporters are racist garbage.
“A nation can survive its fools, and even the ambitious. But it cannot survive treason from within. An enemy at the gates is less formidable, for he is known and carries his banner openly." "But the traitor moves amongst those within the gate freely, his sly whispers rustling through all the alleys, heard in the very halls of government itself." "For the traitor appears not a traitor; he speaks in accents familiar to his victims, and he wears their face and their arguments, he appeals to the baseness that lies deep in the hearts of all men." "He rots the soul of a nation, he works secretly and unknown in the night to undermine the pillars of the city, he infects the body politic so that it can no longer resist." "A murderer is less to fear..”
― Marcus Tullius Cicero
