Youtube, like Facebook, is starting to "censor" material that gets reported as "offensive". A FB friend had all of the pictures of his dog removed as "offensive". My guess is that they use a robot to handle all this work so it never looks at the material. If you post something conservative, expect to get reported.
One of my childhood friends married a conservative video blogger who shows up on FR all the time. I'm pretty sure his Youtube channel is getting hammered but he has sponsors.
