You've articulated a couple of ideas that have been lurking in the collective concern of ideas here on Less Wrong, but which, as far as I know, haven't been made definite. About why some topics shouldn't have too much light directed at them -- ironically, as you originally claim, in the interest of reason. It's been a very vague concern and precisely because it hasn't been articulated it persists stronger than it might otherwise. I would encourage development of these points (not specifically by you, or specifically in this thread, but by anyone, wherever) .
