Regarding your reference: I looked at some of their other assertions (zebras, koalas, gorillas, volcanoes, gravity, satellites, space, etc.  are fake). Their delusion is astounding. I've tangled with one (who has self-acknowledged multiple sock-puppet accounts). He suggested seriously that women I knew who had become pregnant and given birth could very well have been faking it with prosthesis bumps (for of course they might be trannies). If they aren't trolls, then they are pathologically deranged. And they have never traveled.
