Question

I asked my rabbi about you; he recommended that I keep my distance, but he couldn’t give me an unequivocal ruling about you.
I enjoy reading your writings, but indeed some of the things you write are difficult and controversial.
My resources and knowledge are limited; I don’t have the time or ability to examine each and every detail on its own merits, so I would like to ask my rabbi to give me a ruling on the matter.

Let’s suppose for a moment a hypothetical case, in which so-and-so and his rabbi, Rabbi So-and-so, and Rabbi So-and-so is interested in studying the writings of So-and-so, but does not know whether they are legitimate. Suppose for a moment that you were that anonymous rabbi—how would you act? Would you permit your student, “So-and-so,” to study the writings of “So-and-so”? What would you do? What would you look into?

P.S. Rabbi, I would note that apparently in the distant past this was an acute problem that local rabbis encountered often, since communication and knowledge were limited. So I ask that you not resort to the answer, “Study each thing on its own merits and with a critical eye”; as I mentioned earlier, my resources are limited. Likewise, I assume that the halakhic literature has something to say on this matter.
