Shirley has been considered a nutjob for as long as I can remember. I believe this is different than what I have been seeing coming out of Hollywood the last few years with political and other beliefs. When it comes to politics, I have stopped watching actors who seem to ignore reality to promote values that hurt ordinary Americans.
Actors in general live in Lala land in the course of maintaining their craft. There are a few who are still grounded in reality, but just as I see with race baiters and such, the nutjobs get the headlines.
Look at some of these guys who yell about how bad they had it when their career would be welcomed by many who wished they had attained such fame and wealth. The foolishness coming out of Samuel Jackson and others tells me they are not that connected with reality.
