Your point is noted. However, professional mentalists would all say, I believe, that Larry Becker has contributed much to the highest levels of Mentalism.
Professional magicians would say, I believe, that Larry Becker has contributed much to the highest levels of mental magic.
Larry does not claim to be a "pure" psychic and, in fact, lectured to hundreds back in the '80s alongside Lee Earle as they presented opposing sides of the mental magic/Mentalism billet.
Though I have not seen you perform and have not read anything you have published, you have sounded, at times, credible. To insinuate that Larry Becker, though of a different style, is not of the level and capability of Manor, Kurtz, Berglas, and Bauer is ridiculous and potentially damaging to your believability, in my opinion.
Are you in some kind of cantankerous, querulous, and petulant mood that would lead to outbursts of this type? Or have you just had a bad day?
