"HN mods are lenient". Maybe. But I've be down-karma'd so much I've had to create half a dozen new profiles just to stay above water. I'm a retired senior engineer from aerospace (so, not an ignoramus), I am very curious, I ask a lot of (what I think are) intelligent questions, and invariably I get downvoted (or whatever) for unknown reasons (since downvotes are invisible to me), So I just figure there are a pile of butt-hurt simps here, along with VERY intelligent and curious people. Weird mixture that I'm not used to. In engineering, I got along with virtually everyone. Not so much in this wild-west internet space...
