See, ultimately it doesn't matter when you can just use the organs of the State to disseminate your ideology. This is a study on the difference between conservatives and the Left, and why the Left has been winning in the culture war: our side plays by the rules, it risks its own money to compete in an open marketplace, whereas the Left just uses its operatives in the bureaucracy to bypass things like market forces.
So yeah it's great to point out that no one voluntarily wants to listen to their ideology, but Leftism doesn't GAS about "voluntarily" anything. Doesn't matter that they're failing in radio when they can instead confiscate your earnings and use it to indoctrinate your children in the tenets of socialism (they refer to this as "school").
