I would really highly reccomend using the stanford encyclopedia of philosophy over wikipedia.

Nietchze's slave morality is more about the weak valuing the conditions and attitudes that naturally arise amongst oppressed people. Its almost the opposite of how you are using it. Slave morality is not deifying the master, but instead creating a morality to inhibit the strong. This is why so many chuddy dudes like him, he essentially says that the weak hold back the strong with their cowardice. The master/slave morality is more similar to something halfway between Marx's religion is the opiate of the masses, and far right ideas of cultural marxism, but without the Jewish cabal pulling the strings from behind the curtain.

The idea of making the position of landlord into a minor deity is much more similar to the divine right of kings, in that ownership of land is divinely ordained, or antebellum pro-slavery Christianity, being a slaver is a necessary and holy thing.
