Just look at this 2012 2 Chainz video, “Birthday Song,” with the chorus “All I want for my birthday is a big booty hoe.” The video has enough problematic elements to make a purple-haired Tumblrina’s head explode....So, my theory about this is that the young women who make up the feminist arm of the SJW community all grew up in the 1990s. Every one I have ever met is a Sci-Fi fan -- especially Dr. Who -- which means that they cut their teeth on Star Trek: The Next Generation (TNG).
There could be a few reasons for this. First of all, gamers and geek culture in general are seen as easy targets. They are perceived as indoorsy nerds who were bullied in high school. Perfect subjects to put up little resistance to those seeking to browbeat their hobby into submission (of course, the events of Gamergate proved that not to be the case). But compared to the hyper-masculine hip hop culture, geeks are certainly the easier victim.
Another aspect is race. Hip hop is inextricably black, born out of a resistance to authority, namely the police. Many prominent rappers today are staunch advocates of Black Lives Matter and their songs contain lyrics protesting police brutality. So does that give the entire genre a pass? For every “To Pimp a Butterfly” there are still dozens of songs about big booty women.
Now if you remember, TNG was an insufferable departure from the original Star Trek in its constant fulminating about the Prime Directive and the importance of not interfering in another culture's development. The Prime Directive in the original series was just a plot device: Kirk violated it at will, really, and it never caused bad results to do so. TNG took this idea very seriously, though, and I'd wager that growing up listening to important-sounding lectures from Captain Picard made way more impression on these young women than they are prepared to admit to themselves.
So what does that mean? It means that hip-hop comes from another culture, implicitly a lesser culture, and non-interference is the right response to it. The same is true, I think, of their view of Islam. The reason they view it as racist and xenophobic to criticize Islam's treatment of women is that, in so doing, we're trying to force a (again, implicitly in this view lesser) culture to adapt to our preferences.
White male geeks, however, are very much from these feminists' culture. They like Star Trek and comic books just as much as you do! Of course they have every right to tell you what to think and how to behave.
There's an implicit racism, maybe, in deciding which cultures merit protection from the Prime Directive. In the show, it's something like non-spacefaring cultures if I remember correctly. In this application of the concept to the real world, deciding to "respect" these cultures' right to non-interference is in fact a form of disrespect. I don't think these young women would admit to themselves that they think this, or that they are doing this. The last thing they would want to do, consciously, is 'colonize' these cultures or set up a hierarchy in which some cultures were superior. The mental pose is that they're respecting these cultures by leaving them to develop independently.
I think they probably really believe that "respecting you" is what they are doing, rather than "babying you" or "isolating you" or "looking down on you." They would probably be highly insulted at the suggestion that they had any such intentions.
