Not for folks on the right, anyway. Organized or spontaneous, the cops, Feds, and their street allies in Antifa and BLM will shut it down, however benign. Back in 2008 or so, ordinary citizens rallied under the Tea Party moniker (and not much else) and were routinely blitzed by semi-organized leftists engaging in full-contact “counter protesting.” Families and seniors were chased away from ever doing that again. They weren’t ready for left’s style of “protesting.”
BLM and Antifa, however, may organize with impunity. The can peacefully protest by day and “mostly peacefully protes” after sundown. They show up in “black bloc” (or whatever their riot/protest gear is called) ready to throw down. They have brickbats and frozen waterbottles prepositioned in places where they expect a confrontation. Few dare to form a line to counter them. Even the police use extreme caution when engaging them.
Patriot Front is a different fish. It’s what the establishment and street leftists insists the right has but has never exhibited: an organized group ready to confront the left and do battle. It’s the sort of thing that _had_ to be invented by them so that they have something to point to when making their absurd claims.
If the Feds were inventing a fantasy false flag group wouldn't they be pretending to be Nazi's or KKK, and carry swastika flags or wear KKK regalia and have signs with rudely offensive slogans?
If this is an "agent provocateur" group it is the mildest one ever fielded.
