Well, Ben Solo is technically also a Skywalker so it depends on how you see it.
I agree with that assumption but look what they did with him; he’s a buffoon. He’s a completely incompetent and nonthreatening villain. He continuously gets beaten by a random person with no training.
Kylo/Ben does not get beaten by Rey (I presume she’s the random person you refer to) in TROS. It’s quite obvious in their encounters that he’s on top of things. He refrains from striking Rey down because he believes she’ll join him, eventually. You might not like the plot or story or characters or whatever, but please avoid spreading false claims about this movie.
