#3, I am not trying to put words into your mouth. The above post is what I based my point on. There is a whole world of difference between the gnat and the log, you failed to make that difference clear, hence my misunderstanding.
Relatively speaking, there's a world of difference between a kitten and a stone. You seem to be saying if it's not human, it's not worth worrying about, that crushing kittens isn't that much different than crushing stones. I think Matthew makes clear that there are infants, then there are kittens a little farther down, and then there are rocks way down at the bottom. Life is life.
