Aren't conservatives always arguing that actors and celebrities should just shut up and stay out of politics?

There's no doubt that some of the less thoughtful conservatives hold that specific view. The correct answer though is that there's nothing wrong with expressing one's opinions. The problem many conservatives have is when they are paying for entertainment or to see someone perform, and in that context the artist goes off on a political tangent, the people in the audience feel as though their time has been hijacked.

They didn't realize they were going to be attending a political rally, thus they feel like they got ripped off. There's also a certain arrogance/ignorance associated with someone who preaches to the audience he is entertaining, in his assumption they must share his or her political views just because they may appreciate his artistic endeavors. Then there's the silly idea that by freely criticizing someone's views or boycotting them through freedom of association, you are somehow infringing on their freedom of speech.

Freedom of speech does not mean freedom from criticism ... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
