The hard part is that reddit is majority liberal, so it's very very hard to find a good balance.

Any random non-political subreddit is going to be liberal slanted. In order to find a conservative slant you have to go specifically to a political conservative subreddit.

Neutral: /r/neutralpolitics /r/geopolitics /r/politicalfactchecking /r/truepolitics

A spectrum of subreddits across ideological views, all with discussions you may actually learn something from. You’ll notice that none of those subreddits have been suspended because their members and moderators are repeatedly calling for violence against their political opponents, nor are they just recruiting boards for Stormfront. Again, finding the fringe conspiracy theorists repeatedly calling for violence doesn’t actually give you a well informed or balanced perspective.
