A few months ago I was talking to a (white) guy about social movements and we started talking about the Black Lives Matter movement and race relations in the United States. He suddenly got super flustered and opinionated. He went on a rant to me about how "all lives matter" and how every black person who has been killed by police was doing something wrong and how the police are just doing their job. I fought this notion, and began telling him facts about different cases but he literally refused to listen to me.
