Matt Stone & Trey Parker On Making Fun Of Liberals

From an interview with The Huffington Post:

They have certainly mocked conservative groups and people on their show, but they tend to skewer liberals more often. Why? "Ripping on Republicans is not that fun for us only because everyone else does it," Matt explained. "It's so much more fun for us to rip on liberals only because nobody else does it, and not because we think liberals are worse than Republicans but, just because..."

"..it's like fresh snow. I mean how're you gonna rip on Sarah Palin in a new way?" Trey pointed out.

"I think sometimes we do gravitate towards things other people haven't done and a lot of times that makes us gravitate away from ripping on Republicans cause it's just done very well by a ton of people. It's hard to compete with Jon Stewart, etc -- those guys are brilliant."
