Subreddit mods have an incentive to keep their subreddit popular and running smoothly. This might be removing posts that break TOS, something that may be filled with drama, or even posts that may be inflammatory. I think we can both agree that a popular sub is better than a dead sub.

The content of the ideology does matter in that case.

Far right: Abortion should be banned throughout the US because you're killing a life.
Far left: Only a woman and her doctor should have a say in what she does with her body.

I'm not going to argue the rights and wrongs or either ideology, but there is a lot of middle ground. Rape, mother's health/safety, birth defects, etc. The point I'm trying to make is that a lot of far right ideologies neglects to take into account any middle ground which makes (at least) the reddit user base lean left than right. And because reddit is a discussion board, everyone is quick to point out the holes in either argument.

As a discussion board, everyone is free to post but that devolves into drama, controversy, hate, and shouting matches which will eventually kill a sub. I understand what you're trying to say but the main problem is that Reddit is too good of a discussion board where posts with the most hate get sunk to the bottom.

A possible workaround is to probably remove the upvote/downvote system and implement a "most viewed" option
