Other than the fact that musicians and music have been victims of censorship? Other than the fact that musicians had to overcome attempts to censor music? Whether it is ragtime or rock 'n roll or gangsta rap or even classical like mahler. You would think a profession that depends on free speech protection would be more sympathetic to free speech.
Also, in many instances, you can predict someone's political views with some accuracy just by their profession.
Other then the fact that musicians have been bullied and harassed for almost every facet of their identity in some form by right-wing movements for most of the 20th century?
Literally everything you're saying should make them sympathetic to free speech was perpetrated, in the west, by the right-wing.
Just the "right wing" movements? The "left wing" movements have censored plenty in the 20th century. Go ask anyone who lived in communist china or the soviet union.
It's not a matter of liking "right-wing" or "left-wing". Both are capable of oppression and horrific behavior. That's why I believe in principles like free speech. So that horrible people from both the left and the right can't silence people.
I can't understand people like you. The right wing are terrible because they censored people. So lets be like the right wing and censor?
