There is absolutely no reason to believe actors, athletes, or any other celebrities are more knowledgeable or insightful than the rest of us about political or social issues. Like everyone, they are entitled to expressing their opinions – but those opinions need not be screamed out to the world as they do the actual jobs they are being paid so highly to do. As with most of us in this world, their work and their opinions should have separate venues for expression.
When I order food at a drive-thru, I don’t need to know the cook’s political views in order to enjoy my meal. He can most certainly act on what he believes on his own time, but I don’t expect those thoughts to be seared into my burger.
When I watch a movie, I want to be entertained. When I watch sports, I want to see a game. That’s all. I really just want them to do their job.
