Oh nonsense, reminding people to be polite in regards to certain topics is an abandonment of nothing!
Now, if the Vatican would just call on Islamic leaders to renounce violence, you could certainly accuse them of calling on someone to abandon their principles.
Archbishop Michael Fitzgerald, president of the Pontifical Council for Interreligious Dialogue, told Vatican Radio that the ongoing demonstrations show how deeply Muslims have been offended by the depictions of their Prophet.By the good Archbishop's own reasoning, he had no right to make a statement that so deeply offends my love and respect for the principle of freedom of speech and thought, and should therefore apologize for and retract it forthwith."We shouldn't diminish the love and respect Muslims have for their prophet Mohammed. This is very important for them and therefore cannot be the object of derision or ridicule," he said.
"Cannot" is an absolute prohibition. That's not a friendly reminder; it is force.
