Can you name some specific people cheering the riots and destruction?
FYI, there were literally millions of protesters across the US and only a tint fraction caused damage.
The two are not at all equal. A sitting congressperson supporting BLM protests is not the same thing as a sitting congressperson openly encouraging and even participating in overthrowing a free election.
No matter how much the right wants it, the two situations are not even close to being equal.
Both things can be true. I was narrowly addressing your comment that "nobody is really worried" about something that almost actually happened. Indeed, many people are now acutely worried about unhinged conspiracy theorists taking power through a charismatic guy.
Enraged violent people rioted and burned cities, and a lot of the same Congresspeople cheered them on.
