I think that's a clear misreading of the quote. I'm confident that other liberals will agree with me. The statement you attribute to her—advocacy for parents killing their children—would be reprehensible in my eyes, and I'm confident that other liberals will agree with me on that as well.

I hope that, convinced as you are that I am wrong about her meaning, you can accept that my reading is sincere, as is my moral rejection of the murderous philosophy which you attribute to her. Our moral calculus is perhaps chillier and more pragmatic than yours, but please do not exaggerate what it includes.
