I do not excuse anyone for committing violence. No jargon required. Call me any names you want ;)
I think you will find plenty of evidence of fascist groups attacking people, so it goes both ways and should not be considered acceptable by anyone.
Who was the president who said he admires someone who can bodyslam a journalist and gets his crowds riled up against any (non-Fox) journalists at his rallies. It's easy to find some 'liberal' (by whatever definition) celebrities who get into fights, but I can empathise a bit when the press hounds you all the time. Nobody is perfect and they should be punished for it. The most powerful man on earth needs to pick his words very carefully as others may act on them.
I consider Trump a bully who gets others to do his dirty work and who cosies up to other bullies. The most dangerous bully is one with the nuclear button. Just my opinion.
