You are intentionally proposing that he/she read books which, if he/she comes from a traditional Orthodox home, would be taboo. You yourself acknowledged the anger of your R”Y when he discovered one of your books. Yet you call these books “the basics” and gush about how “No one who aspires to be a Jewish intellectual can be without…” and how they are “books which enable the reader to formulate his/her own views on Judaism”. What do you call that if not proselytizing? It is for good reason that these books are taboo – they inspire nothing like what you claim. Rather, they draw the reader into the skewed version of religion that the authors present as truth.
Never mind that the OP was clearly asking for recreational reading, yet you used this opportunity to try and ram your hashkofos down everyone’s throat. When I clap “Al Chait”, I have in mind the reading of some of those books you mentioned. Have mercy on a yet-pure soul. Once in, these krumkeits can never get back out.
