I'm sure Rudy's speech isn't about abortion. If Cardinal Keeler doesn't want to attend because of Rudy's views on this matter is one thing; however, Rudy was selected by the college because of his courage and leadership.
We don't entirely agree with every speaker's point of views, and it's not necessary either.
So if he was a neo-Nazi or Klansman, but wasn't going to talk about it, the cardinal should attend?
Ought Loyola College to award an honorary degree and status as primary speaker at its graduation to someone who says that Nazism or Communism was just another political philosophy and admirable in various respects? I don't think so either.
It ill behooves institutions using the Catholic trademark of a Faith that teaches that 45-50 million dead innocent babies in the USA are victims of judicial/political murder to honor a political opportunist (he probably recognizes the reality of abortion as murder privately) of any Faith much less our own who claims that it is OK to kill the kids.
Our society can and will pay the price for those 45-50 million dead innocents. Our society has no business expecting the Catholic Church to ratify the societal crimes of SCOTUS and the USA against the unborn.
Whatever his virtues, until Rudy publicly repents, he is not fit to address any Catholic institution, not fit to be on stage at any Catholic function, and, like John Kerry, not fit to receive the Eucharist. Catholic property (like Loyola University claims to be), is as much in control of Catholic authority as your front porch is in control of your personal authority.
