Well, I think we are at an impasse, and I have little desire to continue this train of discussion. If it looks like plankton, it can be treated like plankton, and thus killed when the mother is inconvenienced. If it looks like bacteria, we'll just use a little elbow grease and spare as many as possible. We'll save all pigs and bacteria, but eat onions and allow abortions. The crushing logic has me defeated, but I'm so stubborn that I'll stick my archaic Judeo-Christian/Mormonite views.
PS I recommend taking prednisone. It will lower your immune system and thus save countless bacteria on a daily basis. Plus it will reduce the swelling of your ego, now that you've clearly won this debate. ;)
