Not OP. When considering this line of thought, I think of meme's in the original sense of the word. So one could take a mildly-conspiratorial take on it and say that the "meme" itself stands to benefit from this sort of division rather than a nefarious agent or group. It's a self-feeding cycle because I would argue that this cause done in a bad/unfair way sows more racial/gender/etc division and as such creates more reason for itself to exist.
