Honestly? It's the things you think are beyond criticism that most need to be criticized.
(and especially SICP, which inspires such a dogmatic belief in its advocates that it really ought to just be considered a religious text at this point)
No not really. SICP doesn't, whatsoever, inspires any sort of dogmatic beliefs. And I think it would be more appropriate to discuss the subject (SICP itself) rather than discuss what it's advocates says about it.
Simply put, it's more than an excellent book in the world of Computer Science. It is concise, clear, straightforward and challenging. And I think a text like that deserves every interest and respect from every computer scientist.
