I don't think so. However, I do think yours is somewhat uninformed.
Rosemary was not "retarded", as the MSM now chooses to call her. I defy you to show proof that she was. She had behavioral problems, and Joe Sr. couldn't have that in his quest for his sons to become a dynasty. So she was lobotomized.
By the way, ever hear the story about how Joe Jr. died? He was on a very, very dangerous mission to one-up Jack Kennedy for his PT-109 exploits. I guess you could say Joe Sr. was indirectly responsible for that one as well.
I do not have access to the medical records of Rosemary Kennedy, and I doubt that anybody else on this board has. A woman has died and her death is being used as an excuse to vent on the Kennedy family for political reasons. I have read this and other threads on the lobotomy that Joe Kennedy had performed on his daughter, and although there is a lot of heat, there is zero enlightenment as to authenticated facts. Not going along with the general assumptions about the matter does not put me in sympathy with the Kennedy's politically or otherwise. I actually have read a good many books on the Kennedy family over the years and there is more than one point of view about the state of mental development of Rosemary Kennedy. I make no judgment on her treatment as I have no facts to base an opinion on. I do think that the theory that Joe Kennedy had the lobotomy done for male chauvinist reasons is a crock. Pop psychology at best. He was a repulsive and ethically bent person IMO, but not such a monster that he would deliberately destroy his child's brain.
