But there's a critical mass of lunatics. People whose deep-seated beliefs are not only inconsistent with reality, but not even internally consistent. They can be relied upon to act destructively.
My kid was USAF with really high clearances and I used to tell her regularly “If you ever get to Area 51 and there really are Aliens, PLEASE beg them to take us with them”.
And even if I WAS serious about it, it would STILL be saner than the idiot in that picture and her millions upon millions of likeminded morons.
