It's kind of an inside joke on reddit now how left-leaning /r/politics is. It frames itself as a generic political news page but it's so biased it's incredible.
Unless I missed something, there's nothing inherent in /r/politics that requires it to be a dispassionate collection of links that represent all sides of the political spectrum. Don't get me wrong, it's a pit of human misery that I've long since removed from my subreddit list, but it's what users want it to be.
This is coming from a 2x Obama voter and lifelong liberal btw.
fwiw, it is extremely easy to label oneself thus and not be "left leaning" in any meaningful respect.
Where I differ, I suppose, is against the left's general trend towards censorship, anti-free speech attitudes, anti-police attitudes, and this moral preening about immigration (I believe in borders and the importance of cultural assimilation if you are an immigrant, like I am).
It's a horrific source on information on politics, which makes it sad that it is so popular. Unfortunately there are lots of subreddits like that. I can't read a thread in r/conspiracy without feeling bad about the human race. It's a fun (?) game to guess how people can spin any given event. Great rubbernecking material though.
I know it would be incredibly hard to moderate, at least at first. I'm just not sure there is really a desire for such a place since most subreddits seem to be safe-space/echo chambers.
