Especially dumb because these are fucking noble houses, the criteria for being a lannister is being born in house lannister, there's no other requirement or qualification. It's not even like a Harry Potter house where you can be like "well if I was in this world I'd be in this house" no motherfucker no matter how much of a social darwinist asshole you are you would be one of the peasants crushed under lannister boot dumbass

In short:
