This is a good point. I used to frequent DemocraticUnderground back in the 2004 days during the Kerry campaign. It was as bad an echo chamber as anything we see today. The alternative site was FreeRepublic (or 'freepers', as we called them). However, the fact that you didn't have to go to that site or see those people's opinions if you didn't want to, made a big difference to how vitriolic the whole thing felt.
