Mayor Julian Castro is raising some eyebrows as he is set to speak today at Notre Dame University, with some Catholics saying a man who supports gay marriage and abortion rights, should not be speaking at a Catholic university, because the Church opposes both of those positions, 1200 WOAI news reports.


  "I certainly respect the idea that people have a different perspective," the Mayor told 1200 WOAI's Michael Board.  "That's what universities are about."


  But a conservative Catholic group says Notre Dame is straying from its principles, by inviting as a speaker somebody who as 'strayed' from those principles.


  "You can't just have people who just agree with one perspective, or you're not a university," Castro told 1200 WOAI news.


  Notre Dame e-mailed a statement to 1200 WOAI news in which it said it is 'inevitable' that many of the individuals who are invited to speak at the Indiana university 'will have opinions that are contrary to our own.'   But it says Notre Dame has no desire to 'sequester itself from the world.'


  Castro's talk is expected to be about his development as a community and a national leader and about challenges facing America's largely Catholic Latino community, and he is not expected to bring up either of the controversial issues.


  Castro is a frequent speaker at American universities.


  Similar issues were raised when President Obama spoke at Notre Dame's commencement ceremonies in 2009, although at the time the President was not a supporter of gay marriage.
