Art is a reflection of society, and that includes politics. And art of all mediums, should be given the right to free speech, which also means people expressing their political views. Though I think what some are responding to is the OVERT political messages constantly shoved in people's faces, and often leaning in one direction. And often times people do want to use art and especially entertainment as a means of escape, which means escape from the negativity and complexity of society and politics. So it's a tricky issue. By no means should people be censored from expressing political views or messages in art and entertainment, but at the same time, you could see why people who seek an outlet would want forms of these mediums totally free of these political bents. I often feel the same way. It's part of the appeal of watching, say, a baseball game for instance.
Additionally, when you shove in overt political messages, you risk alienating a good chunk of your potential audience, because not everybody is going to agree with your views, so you immediately are risking repelling a certain amount of people, particularly through overt and not particularly well communicated or intelligent political statements.
My two cents..
