@GouveaKame@Dootch@BiblicGrounded To make my position relevant is to appeal to shifting the burden of proof. The one making a claim is who holds the burden.
A Christian is someone who makes Jesus Christ the central figure of their faith. Beyond that, different Christian traditions disagree about many doctrines. Defining Christianity according to one denomination's additional requirements simply assumes that denomination has the authority to define Christianity for everyone else.
@TaglesTopGuy That is precisely the fallacy--you are creating a strawman version of a Christian that believes in something you don't--then using that as the criteria that disqualifies them from being a true Christian.
The fallacy is claiming authority for a particular set of "minimum requirements" without demonstrating why those requirements should be accepted over the competing criteria proposed by other Christian denominations, even LDS. It assumes the conclusion by defining Christianity according to the speaker's preferred doctrine.
