I must lead a sheltered life because I never heard of him before. My opinion is that he is either very gullible or putting spin on what he says. The whole Jehovah's name thing is quite silly because if he did a limited amount of research he would know it was an incorrectly translated name (a hybrid name) that many religious people feel the witnesses are welcome to.
Anyone who has done any research on cults would know that it is common for cults to have 100% unity on their faulty beliefs.
Since leaving the witnesses I have been to lots of churches of many denominations and I haven't seen one yet where race was an issue so they haven't cornered that market.
If he believes in the Bible and undstands what it says about false prophets and has an understanding of the track record of the Watchtower and it prophecies then he would have to label them false prophets.
I can't believe anyone would take this guy serious but I guess he feels very scholarly and important so let him have his fun.
