It's disingenuous to pretend like "black lives matter" is merely a phrase that any decent person should agree to without question. BLM is a political group with a radical left-leaning agenda that encompasses much more than just "don't kill black people randomly" as you suggest. Discussing these things in the workplace inevitably leads to the accusation that if you don't support BLM, you must not think black lives matter. It's a very cheap tactic, akin to saying that you're not a patriot if you don't support the PATRIOT act.
