I was thinking about your syntactically interesting phrase 'sexual freedom unconstrained' just now as I contemplated some posts in the Game of Thrones WC thread. I had to find your post to see if you used the word family. Characterized by both the gothic family fetish and sexual freedom unconstrained, Westeros is a civilization with the family as its polestar & libidinous zeal common like dandelions. Marriage is crucial but not traditional in our sense of traditional marriage; courtship is like the kama sutra; & procreation is key to family survival, key to everything.
Martin deconstructs the family in every way possible, including all of the taboo tropes, bastardos everywhere, prisoners of war being raised in enemy families, familial diaspora, ritual killings, fratricide everywhere. The family members hate each other even more than they hate their enemies.
