I can refrain from talking about liberty. Really. And I've proved it.
It helps if those around me don't start pushing their Statism. There's only a certain amount of Statism I can tolerate before I speak up.
Over Christmas when we were playing Password (an edition that came out before I was born) and when someone gave the clue "criminal" I guessed "government". That wasn't the word they were looking for. The next clue was "savage" which still fit. But the word we were trying to guess was something else-- that I don't remember now.
Other than that, since no one openly pushed their religion of Statism over the holiday, I didn't feel the need to say anything. Someone even got a gun as a Christmas gift (not me, although I did get an awesome gun accessory) so it was a liberty-friendly holiday.
