I think these people do not go nearly far enough. I think they should ban all food for Muslims as pretty much every single edible thing today is a direct result of genetic engineering, reaching back to the Catholic monk, Gregor Mendel, and right up to the (probably) atheist, Norman Borlogue, probably the greatest human being who ever lived by any rational standard. So I say “Go Muslim morons go! Ban all food altogether for Muslims! That will sure show us!
The link for Norman Borlogue goes to an exceptionally good episode of Penn & Teller’s Bullshit about feeding the third world and the lone scientist who made it possible.
I put the link in to go right to that spot. But I recommend seeing the whole episode from the start.
