That's because you're not Catholic. For us, the Pope is the Holy Father. Next time you hear slurs against the Pope, please consider what it would be like to hear the same slurs against your own father. That's what it feels like.
I'm not suggesting that any criticism of the Pope should be banned -- he is a public figure after all -- just asking for you to see things from our perspective.
Fair enough
Do Christians feel that way when the true God of Abraham, when Jesus Christ is insulted? Are we supposed to? Has not the Lord God already defeated His enemies? Does it edify us to feel insulted when wrong is spoken of the Lord? Does that show our faith in Him, or lack thereof? Perhaps we should all take a long deep trip through the Psalms!
