Actually, it's those newest to the faith I'm most worried about. The wide-eyed table-thumping evangelistic zealots preaching fire and mesquite coals, or oak, or what have you. Giddy with ketosis from their most recent repast, practically ecstatic, sometimes speaking in burps and groans. These are the ones who radicalize and promote barbecue jihad. It's tragic.
Let's not forget about the zealous adherants to "propane and propane accessories."
