FOSS is politics. DNS is politics. Stray dogs is politics. The weather is politics. Banning political discussion is politics. Any disagreement or difference of opinion is politics.

There's usually just something missing from sentence e.g. "No politics (that I don't agree with)!" or "That's censorship (when they do it to people I agree with)!"
