The Ba'hai's are apostates themselves. They are viewed as apostates of Islam.
They have interesting history and teachings. The Ba'hai's are very different than the JWs, yet, at the same time, they have developed into an organizational hierarchy that is uncomfortably similar to the WTS. They have recently established a 'governing body' that is in charge of all things Ba'hai.
Notably, the Ba'hai's have a very different view than the JWs towards education. They promote higher education and also hold all of the creative arts in high regard.
