I was trying to discuss the principle of whether all life is equally valuable or whether some discrimination is possible.Same answer applies. (now who's doing the "micro focussing"? )
What was the principle you were trying to discuss again? You didn't say.
You have given your answer, which is an absolutist one in line with Jainism. I'm curious how you manage to put that into practice, since it involves avoiding the death of any insects or other invertebrates, but that's your look out. Either way, there is such a gulf of axiom between us that there's no point even trying to discuss the issue further.
