reddit has a long history of doing away with the most famous toxic subreddits while allowing other nearly identical subreddits to exist as long as they aren't getting significant media attention. for every scandalous subreddit you hear about in the news, there's a hundred more potential controversies just waiting to be discovered, and no proactive enforcement of any rules or community standards.

A chain is only as strong as its weakest link. So whilst dead children might be off limits, /r/the_donald is still around despite the whole pizzagate shooting.

Wouldn't your statement be equatable with "Churches are still around despite some crazy attacking an abortion clinic"?

Apparently we will gladly give away our rights and freedoms to hurt "the other side".

Churches aren't supported by ad revenue.
