Excluding people will only lose support, instead they should've pushed for more social media post on explaining in an objective way why police brutality and racism exist, and how it will impact us (not only African American but POC as well as innocent civilians).
Change happens at the edges, and sadly people deal more and more in extremes + absolutes. There's not much room for nuance.
That depends on the size of the movement. "Support us or lose all your friends" is a valid tactic that has been successfully used since long before written history. Requiring members to perform an action (unfriend people, post harsh messages, etc.) also induces deeper commitment (psychologically and materially) then merely someone saying they support a movement.
I'm merely pointing out that violent rioters will elicit negative responses from people who don't want society to burn down and those who stop said rioters will elicit positive responses.
We can go down the path of how much has been built by slaves, what you mean by enslaved, and how I am somehow responsible for that, especially as an immigrant from a country torn apart by American imperialism.
You are not the judge of what is an aweful human being, seriously, you’re just not that free of sin or amazing.
In your smugness you no doubt increase the wealth of other such “aweful human beings” by working for them, paying them for goods, paying taxes, etc.
This attitude is tiring and counter productive.
