All muslims are not going to practice Islam in the same manner, that is a fact, we have to learn to be tolerant of differences or else we are heading towards violence. Calling others names such us innovator etc is a waste of time, leave that to Allah.
Just some hadiths for you regarding this matter
The Messenger of Allaah (sallallaahu alayhi wa sallam) said,
"Whoever innovates or accommodates an innovator then upon
him is the curse of Allaah, His Angels and the whole of
mankind."
Reported by Bukhaaree, 12/41 and Muslim, 9/140
