I happen to know Ken and his wife. I have to say forcing oneself to believe greater and greater stupidity seems to be taking a toll. Sadly for bethel heavies of this age their life is 80-90% over and I think they will go down believing with the ship.
I'm not sure how a witnesses can listen to these "logical" gymnastics (about the baptism date) and not feel totally uncomfortable. There is a heavy underlying current of blundering confusion.
