I agree that respect and civility are goals worth working at.

Unfortunately, anti-gay hate crimes are on the rise even in the first world (doubled in the UK in the last 4 years, on the rise in Europe and the US ... transgender folk being routinely murdered ... corrective rape in South Africa rampant ... that's my neck of the woods).  

There's no polite dialogue with Adolf Hitler (even though we daren't impugn his intentions ... that would be a really egregious crime!).

Clerics who equate homosexuality with the stuff of Satan and the destruction of civilization feed directly into hate crimes. Of those to whom much has been given, much is expected. Of those to whom much is entrusted, even more is expected! Much is entrusted to our Cardinals!

Pax et bonum.
