Well, we have two demons in a club, one angel at a church and Count kicking the absolute shit out of a rapist in the alleyway behind said demon club. Feel free to join anyone really. 

I'm going on the logic that it wouldn't matter who is in charge of the area, rape is still going to be a problem. After all, it is an act in which the doing it gains the freedom to do whatever they like to someone by denying them theirs so it seems like the kind of thing that happens regardless of if it's a demon or angel controlled area.
