Oh, man, I gotta say it. For me, what is the most maddening thing about human beings? There are many to choose from, but Crazy Thing #1 for me is the fact that there's some nutcase running around, he's batshit crazy, he's not getting the medication he desperately needs, etc. BUT this total wacko is well-respected, people take him seriously, clueless mainstream media-types write articles about him, he's got a good-paying, high-prestige job, blah blah blah.
In short, humans are staring crazy right in face, and they don't have the psychological wherewithal to recognize it! They're not competent enough to see it!
I see this incompetence over and over again. Well, that's Flatland for you.
