I hate when people compare Hannity, Beck, or Rush to Bill Maher. There is a huge difference. Bill Maher is a comedian talking politics. Rush is a political radio host. You don't see Rush going on tour doing comedy gigs.
I was trying to be fair by comparing them. Maher is a comedian. Limbaugh was a disc jockey. Neither one are politicos or journalists, yet both do shows on politics. And while I don't think Maher is nearly as inflammatory as Limbaugh, he has and does say "extreme" things, sometimes just to piss off the conservatives.
