It used to be that way, with high diversity of opinions between subreddits.

These days, all the default subs are left leaning, most are far-left leaning, which means most users have a partisan experience. This then impacts the overall makeup of the site’s userbase which cascades this bias through every other subreddit.

Sure, there are a small number of relatively low traffic communities that have held out, but they are now an insignificant proportion of the content on the site.

Fortunately, you still have communities like Twitter/X where neo-Nazis can feel at home.
