The other day, I was reading a Peta message board about "zombie chickens" and it sort of reminded me about dubs that leave but still think it's the truth. If you don't know what a zombie chicken is, after an egg laying hen is done laying eggs, they stuff the hens in a room full of carbon dioxide and gas them to death. The hens don't produce enough marketable meat so they gas them and turn them into fertilizer. Once in a while, one of the hens pop out of the chamber dazed and confused and they kill the hen.
Now a zombie witness is a JW that's been gassed by some of the negative concepts of the non JW world without any of the positive concepts. So pretty much, they're in a dazed and confused state.
I have a feeling none of them are going to be crying for "brains". Hehe.
