And there's a reason why Gendry never had a chance to sit on the Throne even though he was the true heir since he was Robert's only living son.
Gendry didn't sit on the throne for the same reasons that Rhaenyra's kids won't. They are bastards and the realm will not accept them.
Do niggas not understand that the Lords would rather not have a woman lead the realm in the first place? We've known this since the first episode. Just because they pledged loyalty to Rhaenyra when Viserys named her his heir does not mean that they're all cool with it. They're not. That's the same reason why Rhaneys never sat on the throne. The realm will not accept a woman as their leader.
So now on top of the Lords accepting a woman a their leader you are also asking them to accept that same woman's BASTARD sons to lead them as well? That's not going to fucking happen. Alicent knows this. Rhaenyra knows this. Viserys knows this. This is why they tried to convince Rhaenyra to marry and bear a son for over a decade now. She did not want to accept that. Fine. Cool. Rhaneys told her exactly what would happen and she didn't listen. Daemon told her exactly what do do and she still didn't listen. Finally Viserys hand was forced and he forced her to wed Laenor and she still could not do her duties and produce a LEGITIMATE heir.
Rhaenyra took too long to get in the game. She was too busy sulking to make smart moves. She should have a legitimate heir by now. She went on a years long tour looking for someone to wed. She turned down every single candidate. Just think. She literally could've wed the Lannisters, had a son, and still did whatever the fuck she wanted to do just like Daemon told her but she wanted everything to be her way.
Now that she's older she wants a redo and she wants to insert herself into the fold but she's made too many mistakes.
And niggas are really calling Alicent a hater for literally pointing all of this out to Rhaenyra. Shit, if anything Alicent was pushing for Rhaenyra to wed and have a legitimate heir so that all Alicent would have to do is just be a mother to her kids but Rhaenyra was too stupid and she didn't know how to play the game and now she's crying dire wolf.
