I used to get similar types of emails on a regular basis. All of them Urban Myths, All of them from a far right wing perspective and most of them from a racist point of view. I sent out a "Reply to all" email and stated.

"These emails are NOT TRUE, are URBAN MYTHS and I find them OFFENSIVE. Do not send me emails of this kind again!"

I don't get them any more.
