You’re right.
Most Americans have no idea what pizza in Italy is like.
One Italian critic said the deep dish is more like lasagna than pizza.
I grew up eating home made sicilian and mainland pies that my grandmothers made, and my mother. Both grandmas from Italy/Sicily.
They wouldn’t take this stuff seriously at all.
But if you (not nopardons) guys like it, enjoy it. What can I say? But it ain’t pizza.
