BLM opposes discrimination based on skin color.

There have been a number of instances where people who claim to be involved in the movement, that is activists and not necessarily leaders, who have posted comments equating to suggesting harm should come to white people, how white people are evil, etc... There have been a number of them who have had their Twitter account banned because they did those things.

I have tried to pick my verbiage carefully. Members of a group, for better or worse, are representative of that group but not in totality. Thus, generic statements are often not easy to make and leads me to point this out in response to your statement.

Also, I'm part black, if you're curious. I'm definitely not in the group most would expect to point this out. My white genes are a definite minority. ;-)

At any rate, some people who claim to be involved in BLM have made very, very racist statements that absolutely are discriminatory. Some have even gone so far as to suggest acts of violence. A search of 'twitter bans BLM member' should turn up some results, if you want citations.

C'mon, you get to a position of equating anti-oppression movements with oppression only as a result of the most tone-deaf and pedantic mental gymnastics, by stripping out context completely.
