Humor doesn't have to be obvious to be good; and a magician doesn't have to ever give away the secrets of their illusions, no matter how loudly their audience cries out.

But I'm terribly sorry if you didn't get it. Just a simple play on words. It's certainly not insular or community destroying - an accusation like that is simply hyperbolic. Perhaps like most living things, growth only comes when there's opportunity to being tested and stressed.
