OP is angry and in the same county as me, I'm staying indoors for now.

I do chuckle when people complain that dragons don't do what they would like, remember that dragons, although mythical (maybe possibly probably) creatures they have a backstory depending on what they are featuring in but it tends to be rich in the applicable lore.
For Skyrim regard these massive flying reptiles as :-
Arrogant
Dismissive
Ancient
Distainful
Highly Intelligent
Wise
Self centred
Then it shouldn't come as a surprise when one decides to ignore you completely, disrespecting the Dragonborn is something they love to do.
