I am frankly apalled that some other man thinks he has control of my faith. Not what the Bible teaches.
Huh? Nobody's controlling Kennedy's "faith" (whatever it might be!) -- the bishop is just saying he can't receive Communion in his diocese unless his faith conforms to the what the Church teaches. In fact, since he apparently doesn't believe what the Church teaches, one wonders why he bothers to go to Mass and receive anyway (if indeed he does).
The Bishop as a successor to the Apostles of Jesus can certainly deny the Sacraments to someone who so publicly stands against the Catholic Church and encourages and allows others to commit a mortal sin with respect to the life of another human being.
He is not denying his right to Faith in God.
He will face his judgment from God when he dies.
Nobody is exercising any "control" over anyone's faith in this situation.
Someone who claims to be Catholic while taking the disgraceful public stands that these public figures in the Kennedy family have taken over the years is like an Israeli Jew supporting Hamas or Hezbollah.
