I think you're right. I have been to several events where this has been a topic of discussion among people who I would call committed Catholics, i.e. those that attend regularly and are part of parish activities. They appear to side overwhelmingly against particularly the honorary degree. To say no one is listening is way off base and arrogant. There certainly are a significant number of practicing Catholics that agree with the invite and even the degree, but my bet is that there are many more who don't. You can stick your head in the sand and say that they don't count and that no one is listening but that doesn't make it so.
