(spoilers main) What is your asoiaf unpopular opinion that gets you a lot of hate from other fans?
I think asoiaf is not pro-monarchy and is skeptical of power and messianism in general. Whoever thinks that we'll get a clean and cut happy ending with Dany/Jon/Arya/whoever becoming an "enlightened" monarch and solving all the problems is going to be disappointed.
For some reason this view rubs a lot of people the wrong way.
