I don't understand how commenters generalize about Reddit: the is no Reddit, only subreddits - each of which is moderated in a different way. I moderate /r/Africa we deal with speech mercilessly. /r/askScience or /r/askHistorians have even stricter policies. On the other hand, there are subreddits which are most definitely hateful... But I never go there. In the middle, I'm still subscribed to /r/Europe which is a battleground... I won't give it up and I do not see how any amount of moderation could make it better: politics are all about conflicting ideas !
