"While I am hardly a fan of the Kennedy's, I would not call someone a loser because he/she lost a baby, contracted cancer, or was assassinated. The woes brought on by their own hand lend 'loser' credibility to Ted and other progeny but a broad brush is not warranted."
The problem with this article is that it indiscriminantly mixes up the bad things that have happened to members of the Kennedy family and their relatives with the bad stuff they brought on themselves. The intended effect is to make you feel sorry for the "star-crossed" Kennedys. It's a typical example from the dishonest press.
Some of the bad things that happened are the result of risk taking behavior. Flying in bad weather, driving in open cars against secret service advice, risky skiing activities.
This family has genes that are pulling it out of the gene pool.
