I use that power. I say things ranging from “Dude, that’s not ok” to “Are you fucking stupid or something?” if I’m looking to get their attention.
I’ve also pulled out “You know my cousin is black, right?” (true statement) and “That’s my sister” (untrue statement). When you make it personal they get real uncomfortable and start apologizing.
People forget the part. The garage bands who couldn’t possibly make it in the 90s can now release their own music without a label. I’m just a drunk and I’ve got music out there that was mostly recorded in a closet. Anyone can put stuff out and try to find their audience.
The other thing a lot of folks forget is that most bands never made much from album sales. Only the top tiny percent did, even among a lot of famous bands. Musicians have always out there killing themselves on the road to make money on ticket sales and merch.
