Obviously Spoilers ahead for the last episode.
Dany is the representation of the aryan woman. Aryan Beauty and Fertility. She is the metaphorical womb of the aryan race. The Stallion that mounts the world is the potential of the aryan race.
Jon is the representation of the soldier, the traditional man, stoic, masculine values. The giant sword from Mormont he is often seen carrying around is representation of his martial vritue.
Tyrion is a representation of jewish intellectuals. Mind over matter. The pen over the sword. His bad advice to Dany was self-destructive. Not once did he give good advice. Everyting he told her were basically poisonous ideas. These are all represenations of what women today believe and think of as self-evident. Everyone perceives him as extremely intelligent, despite the bad advice. Jews also have a rich history of comedy, so it's not surprising that he is also the quipmaster.
I could write pages and pages of this, but I don't want to bore you all. What happend was that Jon basically let himself be manipulated by Tyrion to kill his own woman. He rejected marriage with her. He rejected breeding with her. Dany isn't actually infertile. She did birth a kid. It was just a disgusting mutt devoid of all beauty and strenght.
And what the viewer noticed was also an extreme sense of dread and suspicion of treachery, leading up to it, that completly evaporated once he killed himself. Not even the Dragon did him any harm. It was all in his mind.
This is the theme of our current gender relations. We are scared of our women. Because they have a metaphorical dragon on their side, that they didn't use to have. The divorce courts and feminist marriage laws.
Dany just wanted to be loved by a strong man that helps her conquer the world and Jon rejected her. Again the theme of sexual frustration ending with a destruction of a city isn't surprising. It basically represents feminism as a giant civilizational shit test for men.
And when they meet in the throne room, we can see that Dany regards Jon with absolutely no suspicion. Do not be mistaken and think that Dany somehow reprents an already tainted woman, because she was married to Khal Drogo and so on. She is the reprentation of feminity and women in general, not a single woman in this context, so she was a stand in for different kinds of women at different times. In the early Seasons, if you remember, she basically called for the destruction of the white race with her foreign, middle-eastern looking husband and ally.
And how did the story end? Jon retreated north. This basically represents the retreat of the white europeans to remote locations and abandoning the cities. While his culture and goverment is devoid of strong masculine figures and instead ruled by weaker men devoid of higher ideals and morals.
But this is not an end for us. When I watched the ending, I kept hoping it's a a dream and when the show didn't utilize time travel to fix the situation, I thought about an alternative ending, where Jon would unite with Dany and marry her to take over the world.
The only thing that prevents us is fear.
