I cannot think of a thing that is free from politics.
We can choose to ignore these questions, but that doesn't mean they aren't there. While they aren't directly answered with "The Democrats" or "The Republicans" or whatever, they pretty quickly have answers that fall into one camp or another.
That's about my feelings towards (partisan) politics. I totally understand the impulse towards politics; I have a preferred political camp too, and I think it'd be great if they achieved more power and influence. But I don't think my camp is so important that it ought to go around intruding on every discussion in the world.
Second, I think my brain is hardwired to ask these questions. To me, it's a systems problem like an engineering problem.
The difference between burritos and politics for me is that the questions I often ask are about people. Who benefits, who is being exploited, are people being treated fairly. I'd use the word justice, but that's a pretty loaded term. When I play a game, for instance, I wonder how people were paid, was there crunch, etc.
I cannot turn this part of my brain off even for things I enjoy. Again, it's like handing me an interesting engineering problem -- I'm going to be thinking about it when I'm not distracted.
Some things are perhaps coincident with the politics of the thing. Whether manufacturing uses sweatshops or child labor, for instance. I'm not sure that's separable.
