Democratic Underground

DemocraticUndergroud.com is a community of Democratic party supporters who feel that the internet already has enough sites that host messages of hate, disingenuous argumentation, smears, trolling, and/or outright lies. Therefore, all anti-Democratic and anti-liberal trolling is banned, regardless of whether that hate comes from the far right or the far left. Most of the reviews here reflect the anger and frustration that individual trolls have at the DU refusing to host their polemics. Within those modest guidelines, the DU has a lively discussion of analysis, news of the day, etc. There are disagreements, most which get resolved amicably. The vast majority of regular Democrats are perfectly comfortable there; moderation is considerably lighter than you find on most political subreddits.

This site is as radically leftist as possible. All posters who write anything that even hints of merely "left-of-center" (i.e. Somehow less than extremist, propaganda-spewing Joseph Goebbles) is immediately banned and the "offending" posts are deleted. This means that most registrants become banned on their first day. There are a few who make it to their second day. There are no discussions, only raving diatribes. I registered and began posting. Within my first twenty minutes, I responded to a poster who claimed that socialists were so much better than Nazis by reminding him that the Nazis were socialists (i.e. National Socialist Workers Party) and I was promptly and permanently banned... and my posts were deleted with haste.
