It's bizarre to me for a religion as public as they are, and as obstensibly devoted to delivering the one and only Message For The Ages, with their tireless pounding on the public's doors, that they are remarkably averse to delivering their message openly -- on the air and in a public forum.
I suspect they know most of their core beliefs are indefensible, and downright cartoonish in their unwillingness to come to terms with unassailable facts of sicence and history relating to evolution, the age of the earth, the flood etc. and know they would be laughed off the stage at any public airing.
