Some democrats may have supported the BLM movement and peaceful protests but I don't recall them calling for violence or supporting sedition. I think there is a slight difference between protesting injustice and rioting after refusing to accept the out come of an election.

Huge difference between the peaceful protests that in some occasions turned violent and what happened to day - violent rioters forcing their way into capitol to disrupt government, chanting "hang mike pence" with trump encouraging their sedition. I don't recall hearing about IEDs being found in government buildings after BLM protests. There was that one shooting at a BLM protest, but that was some kid on the other side doing the shooting.
