There's a long list of things Dewey does not approve of. And, no one alive, besides him, know what they all are.
It seemed to me that the things Dewey did not approve of were poor workmanship, poor gun designs, poor repairs, and fools.... not necessarily in that order.
I cannot recall any instance where anyone was able to prove that any of his sometimes strong opinions or observations were incorrect. When he gave advice, it was well worth listening to. It isn't often that anyone who even approached his level of skill and talent has been willing to share it with us. And he wasn't here utilizing free advertising to sell stock making classes, gun importations, or to sell firearms. I understand why he left this forum, but really wish he hadn't. Nobody here is perfect, but I can easily think of some much more deserving of criticism.
