Why are the left majorly the ones that disrespect Martin Luther King's memory?

I remember during the BLM protests for George Floyd last year, there were rioters and looters during the period. Everytime any person who was against the rioting would bring up the fact that MLK peacefully protested, usually a member of the left will respond "Well, look what happened to him."

Are you implying that only the ones that commit no violence whatsoever are the ones that end up being killed in the end? I'm sorry, but have any of you ever heard of a man named John Brown? A radical abolitionist who used violence to liberate slaves? It's not like he had much a better result in the end.... 🙄
