I think the thing isn't that feminism isn't devoted to attacking patriarchy denial so much as it acknowledges that focusing on that is a losing battle. To be able to see the patriarchal structure you have to be willing to see the vast range of misogynistic attitudes and how they interact and influence people.You also have to be willing to see things for what they are and not believe the pretty and convenient lie. If people are dead set on believing that misogyny looks this one very specific way, then it's nearly impossible to convince them otherwise.. For a parallel look at what's going on in Ferguson and how people will do all sorts of mental acrobatics to claim that it ISN'T about race. So if we spend our energy trying to convince people that the patriarchy exists, we're really just wasting energy (which is a limited resource, because constantly fighting is exhausting) that could be better put to use doing other things. It's just a matter of pragmatism.
The Puerto Rico situation is complicated. Like the government is corrupt, you have to jump through hoops to get a part time job, the public service infrastructure is full to the brim with unnecessary bureaucracy, the population suffers from tall poppy syndrome, but at the end of the day these are all things that have their root in that Puerto Rico is, for all intents and purposes, a US colony, because colonization does crazy terrible things to the colonized. It's really complicated and even though I get why things here are the way they are I still have a lot of resentment towards the place. (Also, it's trying to kill me.)
