in just one paragraph this post has it all:
the totemizing of 4chan as a set of symbols & interests, superficial proximity to any of which has such unsavoury implications as to override any other aspect of someone's personality, politics, ideology, etc
being entirely too pressed about the sex lives of strangers
the suggestion that one's politics (ie, whether one is "leftist") is contingent on one's sexual interests
the phrasing that deliberately obscures the boundary between incest/rape & kinks playacting incest/rape, as if to imply that the unspecified users being referred to are committing actual sa under the guise of kink
sweeping statement about "tumblr"-- if the site as a whole was as described in this post, then how would this post be able to get 5000 notes
"speaking as a white person, [thing i dont like] is white people shit" <- i was under the impression that this sort of statement was considered tacky
"people of colour universally have more conservative sexual politics than white people. this reflects positively on people of colour"
the implication that every person that has ever used tumblr is either white or black, & none of the latter are on tumblr anymore
the assertion that there was a point in time at which tumblr as a whole was "leftist", & now it is the opposite
