Pretending that Rosemary was put into an institution because the "competitive" nature of the Kennedy household was harmful to her is the "myth". She went into that institution because Joe Kennedy Senior had a lobotomy performed on her that pretty much turned her into a vegetable...and the REASON he did so was that he was worried her behavior might prove to be embarrassing to the political aspirations of their family. I'm not sure if I'd describe that as "evil" but it's fits the bill for disgusting.
I am sure Joe Kennedy made that decision based on a belief it would make his daughter better, not worse. But you continue to ascribe sinister motives to everything the Kennedy's did. That only tells us who you are, not the Kennedy's.
Yeah, and I suppose that's why Joe never told his wife what he was about to do to their daughter? The sad fact is that Joe made that decision based on what he thought would make his son's political aspirations better. He didn't want Rosemary to do anything that would embarrass the family. Joe Kennedy didn't accept failure from his children. He raised "winners".
So did you want to show me the pictures of Rosemary attending family functions after her lobotomy? Or did you want to admit that those very nice pictures you provided of a smiling and happy young lady all came from BEFORE that took place because AFTER Rosemary was hidden away out in Wisconsin!
