I had a year's booking at one facility and made the mistake of talking politics with a resident's son (Michigan professor). He didn't like my views and the Admin cancelled my next 7 jobs. What a jerk he was. Never again have I talked politics.
Then there's the other end of the spectrum , the musicians that have become household names,so established and secure in their fame and fortune, that they intentionally become political activists and speakers because they don't need anymore money if the public disowned them tomorrow..
