Seems to me, you are incredibly wrong in thinking "Hollywood" is, or should be considered, pollitically influential.
Why?
What special wisdom do Hollywood actors bring to the table?
Sheesh, they are just people who constantly get cameras and microphones thrust into their faces by the LSM for operating well with a script doing a job that demands they be comfortable working around cameras and microphones.
Am I supposed to think they have any more insight about the world than my next door neighbor?
Whether you & I like it or not, Hollywood is influential.
Personally, I'd rather they produce something other than the garbage they've been cranking out the past 40 years. A few more key players sympathetic to our side couldn't hurt.
