You know manure and the soils produced from composting are literally feces from animals and bacteria, right?

And that manure is an excellent natural fertilizer?

And that outside that, worms exist? And they poop?

Oh, and that if you were to take bird shit beets and worm poop beets and mash them up and extract chemically pure sucrose from both you'd have no way of determining which came from which?

Assuming that you do know all of these things, you're saying that horse shit and worm poop is fine, but you'll be damned if a bird is involved?

I mean, I can see where you're coming from. A potatoe coming from a toilet is probably not as clean as a potatoe coming from a sterile lab, but that's not what you're saying. You're saying that the toilet has somehow altered the physical chemical compounds involved in the structure of the potatoes rather than has potentially added other chemicals to the mix that was the potatoe. The starch is the same in both. The starch = the starch. The starch and the toilet =/= the starch and the lab because the toilet =/= the lab, but those are different arguments.
