I know Mullins well and he is no better than the Soards in the morals department.
Seeing the light is non sense he is splitting for other reasons than the moral activiites that occured by the Soards. My guess it is financial, getting test fees and seminar money the should go to Sin The. This has been the reason for the other splits along with inflated egos with marginal skill.
In fact he had his own controversy which forced him to move from KY to TN related to being amoral. He is in love with himself, when he taught he would show off flexing his muscles wthout a shirt and trying to get to "know" every mother that would acknowledge his presence. Half his class was based on his showing off and trying to create catchy sayings that made no sense.
Mullins teachers are fooling themselves if think that they have to leave because Sin The has not addressed the Soards properly it is Mullins ego and the big gain he got when Sin The placed the splitting schools under his watch. He saw this as an opportunity.
Sin The's fault is bad judgement and cultural differences. Think about the money the Soards have given him over the years. People will focus on their livilhoods first and he was trying to keep everybody going to keep his livlihood. I also imagine he felt obligated to the Soards. This was just bad judgement and lack of understanding our culture.
Basically Sin The is a good person, I've known him for years and he will help his students.
The poor students that think they are "safer" with Mullins than the Soards will have a rude awakening one day.
