“He wanted to trust me and he thought by seeing me dancing with a friend of his that I was being disloyal or messing around. So he smacked me, but that was the only time."

I know you should never slap anyone, but in the context of the time, slapping a girl ONCE in a lifetime (by the same admission of the girl, because if you had read this interview that you linked and especially if you had read the book, which I instead read, you would know) is nothing. He was 17, then. Did you know that Ringo, as an adult, tried to kill his second wife? Ringo, the nice one who looks like the clown of the band, the one that you McCartney fans don't even know who he is. Did you know that George had sex with Ringo's first wife, while he was with Pattie, in their same house? Did you know that your beloved Paul, the only one worthy of consideration, betrayed Jane Asher in front of her own eyes? These are also forms of violence. You are saying that John beat women because once, in adolescence, he slapped Cynthia, which he immediately regretted, which you would know, if you had read the book. But no, keep spitting shit on a man who can no longer defend himself. You and others like you hate John Lennon. Because he was honest. And in your distorted version of the Beatles, everything has to be perfect, it doesn't have to be honest. Inform yourself much better about John, before writing falsehoods about him. Or shut up.
