Whether it's the big screen, DVD or TV, I pay and support actors to pretend they are Walter White, Miranda Priestly, Governor Mike Morris, etc. I don't care what their personal opinions and agendas are. The only thing they can accomplish with their hissy fits, is to turn me off of their acting, as they become real life political prima donnas. I'm sure there are also those who will like them more for their antics. It's simple, if they have the right to drag politics into entertainment, Trump has the right to drag entertainment into politics.
It's not simple. That last sentence is a false equivalence (and also a bit rich coming from someone with a
Pump Up the Volume avatar). Politics and entertainment aren't mutually exclusive concepts that have to be forced to rub up against one another - a piece of entertainment already has its politics embedded within it to one extent or another. Per one of your examples, the entire premise of
Breaking Bad hinges on the absence of universal health care in America as the main reason Walt turns to drug-dealing is to pay his medical bills. This was kind of what Streep was getting at with her line about how "without Hollywood, all you get to watch are sports and MMA". This is admittedly a severe and elitist oversimplification, but she does have a point - the people responsible for making great art are expressing worldviews that resonate with audiences and politics tend to be significant parts of people's worldviews. It only becomes disagreeable when the politics are too overt (e.g. the
Star Wars boycotts), but art is supposed to challenge one's worldview instead of encourage one to withdraw into one's comfort zone.
Even if you are just going to write off Streep and co. as ineffectual Hollywood types who ultimately preach to the choir and don't have that great an effect on the world at large, that's still fundamentally preferable to the idea of a celebrity with no political experience successfully running for President against multiple experienced politicians (and that's without even taking Trump's particularly extreme politics into account). Being President isn't supposed to be a popularity contest, it's supposed to be about finding the person who can do the best job for the country. This is a problem that admittedly goes beyond Trump, but that doesn't mean it excuses his particular success.
