The Dragon Keeper "Controversial?" Hobb and sexuality. *Major Spoilers up to RWC!

[redchild]

Varys rocks
(but to me is sooooo different a character from the Fool, despite the things you mentioned)

I agree they have completely different personalities, and also very different motivations. But their MO's are similar in that they disguise themselves as many different characters and maintain a far-reaching and intricate network of contacts and spies to gather intel.

perhaps he has little to no information about such, and does not want to attempt writing such and doing it wrong?

That's what I think too. Some may consider it a double standard but I don't think he is oblivious to it. It may be that he truly doesn't know the subject well enough to write about it. There was discussion earlier about Hobb never writing about homosexual relationships until the RWC, and even then she never wrote about two women having a sexual relationship. There is also the fact that the series isn't even completed yet!

Neither does he seem to want to hit you over the head in regards to who is gay or not. Besides, it's not like everyone in society (in the fictional world and irl) will publicly announce their sexual orientation. Some, like the Red Viper, are open about it, but some people are just more private, and I think GRRM reflects that subtlety.
