There is a major problem with Tumblr Feminism and Social Justice.

• Cliquish structure.
• Ideas that a "true X" has to hold.
• Specialized language and terms that are completely opaque to non-initiates.
• Special terms for dismissing outsiders.
• Hostility toward outsiders unless they've "proved" themselves.
• Reluctance to consider criticism, especially external.
• Responding to criticism by attacking the critic instead of what they're saying.
• Popular Big Names who few dare contradict.
• Certain facts "everyone knows".
• Double standards for people on the "inside" vs those on the "outside".
• Tendency to put everyone in categories, and evaluate their statements based on the category they're perceived to be in.
• Reactions to things are usually based on emotion instead of logic.
• Insistence that people who disagree with one clearly cannot understand the subject.

Now, am I describing Social Justice, or a fandom?

For more, see the Geek Social Fallacies. These facts often apply to Social Justice in general, but Tumblr has a particularly intense form of it, since the mechanisms to spread information are the exact same ones one uses for fandom.

I’m not sure if this is inspired by Captain America, or supposed to be his grand-niece or something.

Whatever it is, I had intended to finish it for the 4th. WHERPS.
