False equivalence. Because there happen to be two parties in the US does not mean there have to be two groups trying to censor Digg. Also leftists could never agree to this shit, we're not organized (pun intended).
You don't need organization to get leftist censorship, you just need a majority (which seems to be the case in most general forums or news sites). Then, a natural self-righteous knee-jerk on the part of every reader gets conservatively-oriented things voted/shouted down posthaste. Surely you've seen an instance on the Internet where somebody says something which may be purely sane and reasonable, only to be followed up by 30 posts of "GOD, WHAT AN IDIOT", "I hate rethuglicans!", and "See, this proves how stupid Americans are, go eat a cheeseburger and go to church!"
Actually... I just realized that both sides tend to "prove" their points with lots of ad hominem. It's just that the ad hominem coming from liberals tends to be a touch better spelled; I think the smart conservatives quickly learn to keep their heads down, so only the dumb ones try to step out into the shit-storm.
