Would you consider Mormonism to be Christianity?

[Skill and Chance]

For the general population of Mormons, yes, absolutely.  For scholarly types who take Joseph Smith's writings and Brigham Young's sermons very literally, it gets more ambiguous.

If you can create a definition of Christianity broad enough that Mormons could be considered Christians, then that definition would likely be broad enough for Muslims to be considered Christians. If you have to water down the definition of Christianity that much, then what does Christianity even mean?

This is pretty straightforward, actually.  Muslims reject the Resurrection.

How is it Protestantism they don't hold to Sola fide or Sola scriptura, They belive there the one true church.
Talked to some mormons last month and they say that the apostles in salt lake city have the ability to change doctirens, like the belief that the decendents of jews made it to amerika before columbus. They don't hold to that anymore. They them self did not identify as Protestant.
Neither are there Christians even tho they claim it. As they belive that one self can become God and that God and man are of the same essens.

Yeah, absolutely nobody with any knowledge of denominations considers Mormons to be Protestants, period.

In their organizational structure, they are closest to Catholicism.  In essence, Mormonism has both a magisterium and doctrinal development.
