Simply because they've said enough derptastic and disturbing stuff lately that they deserve their own topic. Quite frankly, I am rather astounded at how someone attending college and actually seeing the world for how it is could descend to the level of the Social Justice Lunatics of Tumblr, simply to appease Radfems, Otherkin and people who call dysphoric Trans people "Truscum".
The mods of the blog are all seemingly different flavours of lunatic. There are a number of the mods who insist that men are trash, mentioning this often - and with the moral myopia they possess becoming more and more obvious.
They all believe that anything that could ever be interpreted as "hurtful" should be censored, with none of the irony evident to them that some of the things they themselves say might fit that.
As far as they're concerned, they have a concept in mind that "if I do it, its okay, but if the Enemy of the Day says or does it, it is Pure Evil and MUST be shunned."
They also say psychologists should be trained to not be "shitty", which would include legitimizing Tumblr's Special Snowflakes and not criticizing their "identity", even when its something blatantly made up like Demisexual or Graysexual.
According to another of their posts, it is appropriation to feel angry for an "oppressed" group's situation.
They've also, according to another post, offered advice to SJW's on how to stop a logical argument - I literally cannot make this up -
