Why are people supporting the riots?

For the past 4 years we've had nothing but democrat riots and every step of the way I and most of us have been condemning them. But now we're all attending and supporting a pro-Trump riot?

What's with that?

Democrats too. All this time antifa and BLM have been rioting and causing absurd amounts of damage. They've murdered innocent republicans and police officers and even took over portions of a city, not allowing ambulances and police to enter. All that time you were hailing them as heroes and peaceful protesters.But now all of a sudden a pro-Trump riot pops up and it's the worst thing since Hitler.

I just don't get it. From my perspective you all seem brainwashed. Like you'll support anything as long as your party does. So I want to understand; what is it that makes you change your opinions so easily on these matters?
