I was thinking the same thing, Syag Lchochma. It has to be very clear that this man does NOT represent frumkiet in the slightest!! I hope this man does not daven in the same shul as Write or Wrong. I can only imagine what her son would feel like to daven near this mentally impaired individual. If it were my son I would keep a very close eye and make sure this guy stays very far away from my son.
There are so many Gedolim in Israel, maybe you could bring him for brochos and chizzuk to a Gadol. Just an idea.
