Violence is categorically bad, regardless of what the intentions are. Referring to violence as "doing things" purposely avoids recognizing this.
I'm not justifying any particular actions that anyone has taken in specific, just objecting to the categorization that it is always bad. (For example, someone suffering from domestic violence might strike back in an effort to escape.)
peaceful:
1. free from disturbance; tranquil.
2. not involving war or violence.
Ariel Atkins - Chicago BLM leader:
"That is reparations,” Ariel Atkins, an organizer, told NBC Chicago. “Anything they wanted to take, they can take it"
She said that about a riot in which 13 police officers were injured, and at least one rioter fired at police.
This is just one example of many where BLM leaders justified (or glorified) violence.
