ROB – do a google search for TEIQU and Kugel. You will find that this supposedly kosher YU organization recently invited him to speak. And if you read the same article that I did, you will find quoted that they were interested in hearing him speak because they study his “work” in their classes. If his stuff is not bible criticism, I don’t know what is.
Not to mention that I know of such classes first-hand (i.e. speaking to someone who was in these classes) and that you can research them on the YU website.
The kefirah problem is not limited to the fringes of YU. It is YU.
