By the left's obscenely dishonest standard for calling things "mostly peaceful," 1/6 was perfect tranquility. 
Study: America Hit By Roughly 550 Violent Demonstrations in Three Months

The obvious solution to which would be: Stop stealing elections and then acting shocked and offended by revolts 
This literally took ten seconds on Google:
At least 25 Americans were killed during protests and political unrest in 2020
If you can't find evidence that's literally effortless to pull up, I would say you are clearly the only idiot here.

Wow. You didn't bother to read your link, did you?
It lists 11 people killed during political protests. Of those:
Two were conservatives killed after pro-Trump “patriot rallies”.
Of the 9 people that died during 8 different BLM rallies out of the over 7,700 that took place
2 were shot to death by counter protestor Kyle Rittenhouse in Kenosha. Rittenhouse is facing murder charges.
Garret Foster, a protestor, was shot by Daniel Perry who was trying to drive his car through a protest after he had tweeted taking up arms against BLM.
3 people died when people drove cars into the protests and struck them.
One photographer was killed by a homeless man with a gun who was upset that people were in his park.
One was shot dead by police after they claimed he pointed a gun at them.
One was a Trump supporter shot in Portland while confronting an armed anti-fascist protestor who was later shot and killed by Police.
It seems the deaths were not the result of being trampled by the protestors or attacks by the protestors and the most people that died in one protest were 2 killed by Rittenhouse in Kenosha. Clearly with over 7,700 protests and only 9 deaths, the BLM protests were a lot safer than the attack on the US Capitol.
US Capitol - 5 people died during one protest.
BLM - 9 people died during 7,700 protests, most as a result of people not protesting attacking the protestors in some way.
