I think it has everything to do with her race when antics like this will get her a finger wag while others would be shot, killed, arrested or beaten. When people feel like nothing will happen to them for being assholes (i.e. privilege), they tend to have more room to continuously do so. You would have to be drowning in privilege to not recognize that. I’m not even slightly interested in “all lives matter” in this situation.
As far as autobiographies, I’m with you. Read both in elementary school.
