Sure, let's say there is real gold vs fake gold. The fake gold exist, and has the same name as the real gold, and perhaps can decieve a few, but in reality the fake gold is not the real gold no matter how much you call it real, real gold. Now, regardless if one believes in divinity of the Bahai Faith or not, there can only be one real Bahai Faith, and that is the one created based on how Bahaullah layed it out, and how Abdulbaha implemented it, and how Shoghi Effendi farther built its order and House of Justice. These are so clearly defined that in practise any fake Bahai sect would be easily known from the real one, so, virtually it will be extinguished.
