It’s not just politics... I joined reddit when I got my Surface Duo, as it was the only online forum I could find for it (Reddit has long been home to Windows Phone enthusiasts, although I had never joined before).
I then discovered the /tennis and /grammar subs — and the utter puritanism of the mods: you can’t even make a joke about grammar, much less correct any of the mods’ rather incorrect grammatical interpretations. They’re just a bunch of silly, little Czars, so I can imagine that the political content is far, far worse.
It’s everything the left says conservatives are: intolerant, ignorant, and humorless.
Yeah, politics is just the tip of the iceberg. If you really want to be disturbed, look into the lives (or lack thereof) of the powermods on Reddit. Most of those are outright groomers.
