The Anglican cathedrals referenced in the article were stolen in the aftermath of the Act of Settlement. This is historical fact. 

From the RC perspective, Anglicans don't have valid orders. This is not a sneer but a statement of belief. 

My only sneer is at the watered down, milquetoast Christianity displayed in the article, which is not the exclusive domain of Anglicans; sadly Catholics aren't immune to this. The Anglicans have many gifts, among which their music and architecture. They are not iconoclasts like liberal Catholics who tore out the altar rails, and more of them kneel to receive what they believe to be Holy Communion and don't have hang ups about ad orientem.
