I don’t think you know what you are talking about.
You’re apparently unaware that Kennedy divorced his wife Joan in 1981, and had the marriage annulled by the Catholic Church in 1992 so he could remarry in the church. The annulment, according to Kennedy’s biography Clymer, was on the grounds that Kennedy never intended to be faithful to his wife, therefore the marriage was fraudulent. Of course, one effect of annulment, meaning that the marriage never happened according to the Catholic church, is that his children, Patrick, Edward, and Kara, were not born of a union recognized by the Catholic Church, i.e., bastards. I think you need to take another look at what the Catholic Church does (tens of thousands of annulments every year) and quit pretending to be holier than other Christians.
