I think Ronald Rychlak got it right:
I don't know how we are going to resolve issues that surround our very different world views, but I am quite certain that restricting what we say - whether that means barring topics from textbooks or rejecting the use of terms like 'Islamic terrorist' and 'jihad' - is not a good start. Let's first be honest in our language and our discussions. That will be hard, but it is the surest way to the truth. If we get to the truth, let's hope that we can also find peace.
