I'm not even sure that he is a saint..
He was a great and holy leader
You're contradicting yourself and I believe you're not being honest here.
Why would it irritate you if someone believes ABL was a saint ?
It irritates me that some people think JPII was a saint, and I can explain to them why I think they are wrong.
But it does not irritate me if someone believes Joe Doe was a saint. He may well be one or not, I don't know him so I can't say.
I never knew the Archbishop myself, but I certainly lean towards the opinion that he was indeed a great saint. Not many 'great and holy' leaders would stand firm against all of Rome, even while being 'excommunicated'. He may not have been perfect, but it certainly took heroic virtue. If that is not reason for considering him a saint, then maybe you could show us your criteria (other than your pet miracle argument, which seems to be your only defense).
Again, why would it irritate you if someone believes ABL was a saint ?
