If you murder someone because you respect life, then
you're doing it wrong. I'm not nearly caffeinated enough to write a cogent response to this event other than to turn around the old anti-death penalty slogan: why murder people to show that murdering people is wrong? Mind you, I don't think abortion is murder, so the analogy kind of falls apart there, but if your value system is so skewed that you place a half-formed proto-human's life over that of an actual human being then you need clinical psychiatric care.
I'll write more if this stays in my brain during the day.
