I'm at work and probably shouldn't click that link, but once again, I'm not saying that MichaelAnissimov's analysis is right; that's a rather complicated question that touches on some deep and AFAIK unresolved issues in identity formation, though priors point to "no". I am saying that Tumblr can accurately be called a major vector for radical identity politics without contradiction with its other use cases. It's both full of straight (and non-straight) erotica and full of LGBT and feminist activists, and the latter are the more relevant when we're discussing its political influence.
The link is SFW :-)

Tumblr is just a publishing platform. The rise of the popularity of a platform does not imply that those who migrate to it en masse grew more numerous, only that they prefer this particular form of expression. The rise and fall of MySpace did not imply the rise and fall of indie bands.
Through LessWrong, I've discovered the no-reactionary movement. Servery says that there are some of you here.
I'm curious, what lead you to accept the basic premises of the movement? What is the story of your personal "conversion"? Was there some particular insight or information that was important in convincing you? Was it something that just "clicked" for you or that you had always felt in a vague way? Were any of you "raised in it"?
Feel free to forward my questions to others or direct me towards a better forum for asking this.
I hope that this is in no way demeaning or insulting. I'm genuinely curious and my questioning is value free. If you point me towards compelling evidence of the neo-reactionary premise, I'll update on it.
