I've been saying it for years, as have others. UFO study has always been full of crazy, nutty, silly, slimy, hucksters, as well as racists, classists and misogynists. Always. And it still is, and always will be. It's a given.
That's not bad. Well, no, wait. It is bad of course. But that shouldn't discourage us. Call them out. Fight 'em. Show them up. And then get on with whatever it is you're exploring. Don't let the creeps in UFO Land make you give up. Just accept the fact that that is the way it is.
