93% of the BLM protests were peaceful [1] despite protestors numbering in the millions, if not tens of millions - compared to the tens of thousands at the capitol. The most notable violence during the BLM protests was an incident where far right extremists, members of Bugaloo boys group involved in the capitol attack, used the protests as cover to murder cops [2].
To compare the two is disingenuous.
