@farmerman,
It's damn frustrating, these ideas, they seem to snowball.
There's always some gullible person ready to listen, normally I couldn't give a rats ass But when my son starts talking it up, I begrudgingly have to give it some attention, strike some balance for him.
He's a child of the web, so if you know of some sensible site that gives a balanced view, I'd be much obliged.
P.S. I've been looking it up but everything seems to be pro-conspiracy
