I don't find SRS to be satirical in the least. Hateful, sometimes. Aggressive, frequently. Strongly biased? Their bias is spelled out in the subreddit name.

The reason they bubble to the top of so many news articles is because SRS' brand of equality is so strongly polarized in a way which makes for great soundbites. Want to know what's "wrong" with Reddit? Grab a headline out of SRS. Want a view on how to "improve" Reddit? Talk to a SRS moderator.

If you're looking for satire, check out /r/circlejerk/. They do a great job at finding what's so wrong with the posts that hit the front page and satirizing them.

Criticism of SRS comes from their online mobbing, not their satire. They have a reputation for brigading and harassing ideological opponents.
