We need to break this down like Dennis does. What exactly is the propaganda? The classical meaning of the term liberal is the opposite of authoritarian. Conversely, people like yourself just got done saying that policies like Affirmative Action needs to FORCE people into action, which is authoritarian. Therefore, he would refer to that as Leftism, not liberalism. Sites like Youtube, however, deny him access on the ground that it is obscene. What exactly is obscene about it? What we can find on Youtube, however, is a myriad of Left wing propaganda and some right wing propaganda, yet they are not censored like Dennis. My guess is that it is because Dennis is so effective at it.
