You are correct but there is a few differences between what the Democratic voters were doing in Congress compared to the Trump supporters.
At most there were what? A few hundred of those people crying?
The amount of Trump supporters (also a lot of plants too) made every other Protest in before Congress insignificant.
All you need is a few dozen plants to start causing trouble and you now have the starting of a riot (even though it wasn't caused Trump supporters, who the fuck knows at the time it's happening.)
Massive difference between having 12 people enter that building and breaking shit compared to 100's of people entering and 12 people breaking shit.
