I’ve always found it funny how people argue that “a bastard can’t be a king” or “a bastard can’t inherit” when it comes to Rhaenyra’s sons (officially recognized as Velaryons)—even though they’re publicly acknowledged by her and Laenor as legitimate heirs. But when it’s Jon, suddenly anything is possible. Somehow, he’s seen as having a stronger claim to the throne (and dragons) than Daenerys or even Young Griff, despite his status as a bastard.
And that is why I say fuck the lot of them. (It certainly helps them to believe Rhaegar raped Lyanna or at least just kidnapped her, and that she--unike Rhaenyra--was never a passive nor active claimant for leadership despite any laws they'd try to bring up and her own will was never a part of how Jon came to be.)
