I can never remember which way around this is. I think the "beer" is supposed to be free in the monetary sense and "speech" is supposed to be free in the rights/liberty sense, but the analogy doesn't actually convey this:
- Speech is normally both monetarily free and (in certain places) a right
- Beer is normally neither monetarily free or a right. But may make you "feel" free, which is another sense entirely.
Is this a cultural reference I'm missing?
