From a certain naive perspective, it's not wrong. But in practice it's not a useful thing to say. It's a dumb simplification used by extremists who want to spam political ragebait everywhere, social decorum be damned.

You could make the same argument about physics. Everything is made of atoms, so everything is physics. Politicians are made of atoms. Does that mean every "$POLITICIAN does $THING" tabloid story is on topic for physics.stackexchange.com? Obviously not.
