This might make me think twice before getting into any more arguments with creationists.
I did once have an argument with a cancer research conspiracy theorist that almost became physical. He was verbally abusing me and someone alerted my hubby to the situation. When he came over to suss it out, the crazy guy started to poke him in the chest, which did not go down well at all. The idiot was thrown out by the party host never to return, and got his revenge by stealing the host's BBQ from the communal storage area.
I like a nice debate, but I'm a big wuss and I hope I never have to defend my ideas physically!
