Perhaps this has been posted before I started reading hte thread--but in light of several posters saying the official BLM movement condones violence and incites it I looked it up a little bit (given that I had not even realized it was an official group and not just a phrase being adopted by many protestors) and here is, at least, their statement about the Dallas police shooting as reported by CNN. it does not sound like inciting violence to me at all:
"Black Lives Matter protesters
condemned the Dallas killings, calling the attack on law enforcement a tragedy not just for those affected but also for the nation.
"Black activists have raised the call for an end to violence, not an escalation of it. (Thursday's) attack was the result of the actions of a lone gunman," the group said.
"To assign the actions of one person to an entire movement is dangerous and irresponsible. We continue our efforts to bring about a better world for all of us."
and you know, many people claimed the civil rights movement of the 60s and the women's rights movements at the turn of the last century and again in the 70s devisive---often those who like the status quo see anything aimed at changing it as devisive--so far I see more devisive rhetoric from the side that wants to protect teh status quo than otherwise--and while that may be in reaction to the BLM movement, I don't think that makes the movement devisive--it just means people who are already included tend to get defensive when told they might be being exclusionary.
Though, again, I admit to not having looked into specific people and leaders in any sort of detail.
