GRRM is an abolitionist and Dany is his favorite character, and the Targ family motto was used in his earlier writing “Fire and Blood” to describe John Brown’s type of violent abolitionist tactics. The Targaryen family also likely destroyed Valyria because they were abolitionist against the slave empire, with the help of the Faceless Men, and helped found the city of Braavos of freed slaves. Jon’s entire arc is about his wisdom of healing old wounds with the wildlings and reconciling, and letting them south of the wall, and his bigoted small-minded “brothers” betrayed him and stabbed him in the back for it. I believe his arc will also be to reconcile with the white walkers, not destroy them, as they are definitely the ghosts of some old sin of humanities that involved invading the weirwoods and disturbing their spirits. They are nature spirits incarnate, they are described as ghosts that emerge from the wood. They are definitely a stand-in for the sins of humanity against nature coming back with a vengeance and the way to appease them is not through overcoming them with violence but by compromising with them. Giving up some of humanity’s magic back to nature that we had seized with blood sacrifices (I believe the white walkers need to be taken to the Isle of Faces in the God’s Eye where there are Weirwood Trees with Green Leaves that have not been ruined by humanity warging into them and using them for their own ends. Jon will lead the others across the wall to the south just like he did with the wildlings, and he will be hated for it in both cases by those with small minds and small visions. He will probably be stabbed in the back by former allies again just like the first time, with people not realizing what he did or why).

In addition, all the plethora of evil bad guys are total chuds. Tywin, Cersei, King Aerys, Jeoffrey, Viserys Targaryen, Ramsay Bolton, the Mountain, Randal Tarley, the slavers, the Greyjoys, etc. are all shown to be extremely reactionary in their leadership styles and political actions and social views. The more sympathetic and heroic characters like Ned, Jon, Sam, Dany, Robb, Arya, Catelyn and Davos Seaworthy are all very kind and empathic and open-minded people. This is quite clear by their actions and statements and thoughts, as we have many of their PoVs. Tywin allows his troops to pillage and SA openly, he has a ton of reactionary hang-ups with sex and humiliation, he is a total evil piece of shit and you hate him for it. It’s shown clearly to be evil and hypocritical and cruel.
