Same Song, Opposite Aisle
These days there are a number of web sites where people mostly post quotations from news articles and/or commentaries on said articles. (The sources of the news articles don't much appreciate the quotation; there's been at least one lawsuit over the matter.)
freerepublic.com is the right-wing flavor. There you'll find a lot of creationism threads--there are either a lot of creationists or a few really vocal ones at freerepublic.com. (OTOH, there are rational people there, too.) You'll find a lot of religious ranting and bashing of homosexuals, and people who dare point out that GWB is pushing big government despite the posturings of the Republican Party are flamed at great length. There's a libertarian contingent that regularly points out the idiocy of the Drug War, and is just as regularly flamed for their troubles, and simultaneously told that (1) they're too few in number to be significant and (2) they're helping the Democrats by "stealing" votes from Republican candidates. During the Clinton administration, there was a tinfoil hat contingent that went somewhat off the deep end (and considering Clinton, that requires some work).
democraticunderground.com is the left-wing flavor. There you'll find a number of religious threads, mostly arguing that "true Christianity" favors income redistribution and the welfare state. There's an astrology contingent, so one certainly can't say that the left is immune to pseudoscience and other such claptrap. There's a Green contingent who's mostly told that they're helping the Republicans by "stealing" votes from Democratic candidates. There's a large, or at least vocal, tinfoil hat contingent who wholeheartedly believes GWB let 9/11 happen so his buddies could make money, that the Republicans assassinated Paul Wellstone, etc.
To freerepublic.com's credit, they're a lot more willing to tolerate varying opinions than democraticunderground.com, which bans people for thoughtcrime, and back in 2002 prohibited posts that the moderators thought might hurt the Democratic Party...but upon reflection, it seems like what we have here in large part are two batches of True Believers, just working opposite sides of the street.
