Does someone need to 100% support BLM (the political movement) to make an acceptable colleague?
What if someone: opposes racism and thinks police's use of force should be more regulated, but disagrees with some BLM tactics/approach to achieving change?
For example, what if the destruction of property from the protests, or calls to defund the police, actually cause a backlash at the next election and it reduces the chances of anything actually being done. Is someone allowed to make a critique like that?
The bottom line is there actually needs to be a diversity of thought to solve problems, and if you silence anyone who isn't 100% behind your message your not going to make change.
