I keep seeing this brought up on HN. Isn't it telling that you have to go back 70 years to find a good example? At that time, the Democratic Party was still in bed with the KKK. It's not relevant to today's politics.
I replied to "the culture where this kind of behavior is normalized and valued is relatively novel", with the Dixie Chicks as the "canonical example".
Surely, providing an older example that predates the Dixie Chicks, can be used to argue that the phenomenon is, indeed, older, no?
The only thing that is different now is that the shoe is on the other foot. I guess when some people find they no longer have license to be an asshole the transition can feel a bit uncomfortable and needing to learn about these things called 'consequences' that everyone else has been forced to endure must seem a bit strange.
