Well, for what it's worth, I'm pretty staunchly Catholic, but I've never understood this kind of outrage. I understand what Blackwasp is saying, with "Commencement is not the right venue to have someone who is ideologically opposed to something the institution is adamantly for," but I respectfully disagree. If he's not talking ABOUT abortion one way or the other during the commencement (and why on Earth would abortion be an appropriate commencement speech?), what the heck does it matter that his beliefs about it are different? I don't see that allowing him to speak translates into an endorsement of his views on abortion. I would hope a Notre Dame-educated graduate would be smart enough to make the same distinction.
