Where did idea that Bill Maher's some kind of Democratic equivalent to Rush Limbaugh come from?
There is no moral equivalence being asserted. What Maher has done is orders of magnitude worse.
...well, since there's essentially no way for me to point out everything that is just inherently wrong with this sentence, I'll just settle for calling you a cognitively-impaired Republisheep ding-dong and leave it at that.
Okay, you didn't have an answer, so you went ad hominem.
Tell me, then. Just what has Maher done that is worse than, say, publicly supporting Joseph Kony and calling women who use birth control "sluts"?
