Ultimately, it is the WTS policy to decide what to do with. Personally, I would have guessed that they would have put further distance between themselves and this monstrous nonsense that was born in the ignorance of C.J.

Call me an optimist, but I still think they will eventually realize they have more to gain than lose by simply distancing themselves from this.
