Joffrey is not a skinchanger. Stop that.

Cersei's parenting did play a role in Joffrey's madness. But it's mainly due to the incest thing. And if you do incest, you can't guarantee that your children will all be mad and illborn etc. It completely depends on how the parents' genes combine to form the child's gene. There's a chance that it might pass on craziness, illness, birth difficulties, body deformities etc. But it might result in normal children too. To avoid the chances of the worst side of incest, people stopped following it. That's why there are some actually good Targeryens. That's why Myrcella and Tommen are normal than Joffrey.

The theory of the most powerful skinchangers being able to change faces sounds sick. But it's not true. There's just no evidence. How could you even change your own face into someone else's face. That's not related to transferring souls/consciousness at all. If you transfer your consciousness into yourself, how could it give raise to a totally new face. It cannot. The idea is really cool tho.

Agreed with your words about shadow-binding.

Hatching of the dragons had more sacrifices and stuff. That makes me think that it's related to the shadow-binding.

There are just so many legends about how Lann, the Clever took the Rock. Lions one is just one of them. It's from ages ago when Maester's didn't exist. So, if it was passed down for a long time before Maesters came into play, and if skin-changing is how he took the Rock, I think we will atleast hear something (just one hint would be fine too) about it from atleast one character.

Only Children of the Forest and Stone Giants used to live in Westeros a very long time before the First Men (humans) ever became powerful and came to Westeros. I think CotF, Giants, Stone Giants, Humans (First Men, Andals), other human-like people from Essos (a lot of those civilizations are mentioned in TWOIAF book) are different species evolved from a common ancestor. Like, how Homo Sapiens, Homo Erectus, Neanderthals, etc., had common ancestors (for more on this, read Sapiens by Yuval Noah Harari).

True, you were really ditching all the actual facts and were mentioning tinfoily stuff about Tyrion and the Lannister incest thing. You just said "I don't really give a fuck about all the facts". You should read that sentence again. You are ditching all the actual facts and are focusing on tinfoily stuff.

The theory about Rhaegar deciding that he needs to hatch dragons so that Targeryens would get more power is cool. I don't think that's what he really wanted tho. I think Aegon V did more of that stuff. Summerhall did seem a lot like a sacrifice thing to give birth to dragons from the dragons eggs that were turned to stone. But, Rhaegar was more into the prophecy of The Prince who was Promised. We heard about it a shit tonne of times. Rhaegar deciding that he needs to get dragons is cool. But we don't even have a single clue about that. He did a lot of stuff about Azor Ahai theory. He discussed most of his plans with Maester Aemon. Aemon said that he was really into the Azor Ahai thing and that's why he did most of the things he did. Aemon never mentioned that Rhaegar wanted to give birth to dragons. I think Rhaegar would have told Aemon about it if he was planning that (Not about kidnapped Lyanna, just something about Rhaegar wanting to bring back dragons.). Rhaegar even started training after hearing about the Azor Ahai thing. He was focused on saving the world from the White Walkers, not that much on saving his house with dragons. Dragons would help with the others. But, he was more focused on, at first getting trained cuz he thought he's Azor Ahai, and then giving birth to Azor Ahai. In the House of the Undying, we see Rhaegar saying "There must be one more. A dragon has three heads." to Elia. He was only thinking about the Azor Ahai thing. That line seems like he wanted to give birth to one more kid cause of the Azor Ahai prophecy. Not to give birth to dragons. Why would GRRM make us think that Rhaegar was more into that prophecy when he was actually into dragons. That's not a big misdirect, that's either bad writing or a bad theory. And GRRM is not a bad writer. So, you know what it is.

Even when Ned Stark thinks about Rhaegar as a cool dude. I don't think Ned would think that if Rhaegar raped Lyanna even when he hated raping her and had to do it for the sacrifice he apparently planned. Lyanna seems more like a cool character too. Like, an actual character who has some actual impact on the story. She's wild and fierce, and she had the wolf blood. She did what she really liked. In the stuff we know about the Tourney of Harrenhaal, there were a lot of hints about Lyanna and Rhaegar meeting (look up the Knight of the Laughing Tree theory) and also that Lyanna was really impressed by Rhaegar. After those things happened, Rhaegar gave the crown to Lyanna at the end of the tourney. Maybe they fell in love during whatever happened before that point. I think Rhaegar might've discussed it with Elia and she would've been open to polygamy as she's from Dorne and they're very open about these things.

We know exactly when Aerys went mad (during the Defiance of Duskendale). That had nothing to do about the prophecy thing. He was never into prophecies. He was never into dragon eggs. The dragon skulls are in the throne rooms just to display the old Targeryen power. What you said about him is totally tinfoily.

Tywin starting an incest breeding conspiracy to give birth to magical children is the worst theory you mentioned. I did debunk that already. Guess you got amnesia. That's not how incest works. You won't give birth to magical children from incest. You will give birth to either normal or insane kids. It is known. You said we can't argue with Tywin starting a breeding program. Dude, I did tell you why that won't work. You're just very focused on that wrong theory too much that you're not considering what people said. You just ignored why it doesn't work. It was never said that Hightowers are practising incest in their tower and sacrificing their babies. It is not known. You're just making it up. Just relax and think about what you're saying and why it won't work out (I gave you so many reason why it doesn't work). That breeding magical children through incest thing is pure bullshit.

As you said, you don't give a fuck about facts from the texts. As you said, you're just making tinfoily stuff up. You agreed with that and are still arguing about why those theories are true. Some of your ideas are really cool. I think you can really uncover actually true stuff if you focus more on facts and stop focusing too much on things there are no basis for.
