Are you trying to imply that consumption of animals and plants/fungi is the same? What's the point of that argument? I mean, come on, I'm vegetarian and I kill mosquitoes ...
I think it's the same, but then again I'm not a vegetarian. What I'm really trying to imply is that what people decide they're allowed to eat is based on (mostly arbitrary) social norms. Is there anything morally different between being vegetarian and keeping kosher?
Aside: Anyone who figures out how to make salmon produce pork will have a license to print money (kosher pork!).
