If you want to know how's its glorified, victims are portrayed as objectified bodies to master and not characters who deserve empathy.
That's objectifcation, not glorification. Glorification is when you get praise for an action. Portraing an action as something to strive for. Just portraing something as matter of fact is not glorifying it. It can be described as downplaying or making light of it. But again, that's not glorification.
To bring a fictional example. The Ferengi in Star Trek glorify commerce. They strive for more and more money. So it could be said, that in this fictional world that greed is glorified. Although it is from the perspective of the humans, and they do not share those values. The humans glorify diplomacy (not TOS ;-)
Incest is not a code word for rape between family. Incest just means sexual relations between close blood relatives. If you count cousins, those can even marry. And just like non-incest relations, you can have those with consent - but usually not with social acceptance. Baring the cousin marriage.
