Technically, yes, everything is political if you make it political. But you have to make it political first. Petting your cat isn't inherently political unless you bring up the government policies and economical structures that allow you to own the cat in the first place, or compare your attitude towards the cat to a political stance, or something else of that ilk.

In the same way, everything is scientific if you study it scientifically, and everything is theological if you consider it from a theological perspective. It's technically true, but that doesn't make it useful. It says more about the way you think than the nature of reality, especially as politics are a social construct.
