1. The comment above didn’t say “Everything is political”.
2. "Everything is political" isn’t true. One might say that many things are influenced by politics; that’s fine, but downstream influence is neither pure single-factor causality nor equality.
3. "Everything is political" isn’t a tautology either.
Support for #2 and #3: There are things in the universe that existed prior to (and independent of) politics, like the Earth. There are phenomena influenced by politics but not inherently political, such as the phenomena of global warming or measuring the level of inflation. What to do about global warming or inflation is political, if you are lucky, meaning you have some persuasive influence at all (not the case in a dictatorship) and/or don’t have to resort to violence.
