Everyone is entitled to their opinions when asked in an interview. However, if they step into advocacy of such things like gun control or general politics even, then they are failing their role to entertain me. As such, I have no interest in listening/watching them nor contributing any of my money to them via sales, viewing, or any other financial incentive.
Strident people like Natalie Manes or others who mouth obnoxious statements using their platform as an artist to do so break up the bond between artist and public. A similar effect is arrests for general thuggery disrupt a fan's enjoyment of sports. Alec Baldwin and Robert DeNiro may be decent actors but their over the top antics regarding Trump disrupt me from taking them seriously in any of their roles, past or present. It puts a shadow across their "performance" and prevents the immersion into the movie watching a character develop.
Celebrities outside of their expertise are dim wits as most of us are. For me to pontificate on the life of a music star would be ludicrous, for them to expound on constitutional law, research into gun violence, and sociology is likewise. They are simply parroting whatever they are fed and add no value to it other than they approve the message and hope that the masses are swayed by an appeal to authority of the singer.
For them to use their entertainment platform to "preach" their sanctified opinions to the masses strikes me as a failure to give the audience entertainment which is what they are paid for. I am excluding comic or singers that actually are political in nature such as Oliver, Bee, Colbert, Kimmel, TDS hosts. There are certain niche political singers such as Woody Guthrie, etc. as well. A person knows what you are getting with those types and caveat emptor--but a pop singer? a classical music conductor? etc. One might as well be lectured by an airline flight attendant on politics while strapped in your seat. Or by the barista when you buy your coffee, no wait, Starbucks has already been there and done that.
