Most web communities are politically polarized in one way or the other. If you do not like the political stories, Reddit allows you to unsubscribe from the politics sub-Reddit. Or just don't visit the site.
"Or just don't visit the site."
That was the solution yes. YCnews is fairly tame and people are well mannered.
And it's not just political stories that are the problem with reddit. It's the fanatic tone that many users take in the comments of stories that really shouldn't be polarizing.
