He was assaulted by non-security personnel, that's a crime.
The fascism is when Trump brags about his "fans" doing this, and condones it on top of the fact that nobody was punished by law. This indicates violently crushing dissent is okay, which would be terrifying under his presidency.
Also the double standard, if this was "black lives matter" doing this king of stuff they would be called criminals and thugs.
It's sad that you people can't understand common sense.
