I wouldn't call it a fetish at all. It is merely the heart and soul of liberalism--seen in their thirst for abortion, the Margaret Sanger PP slaughterhouses in the inner cities of America and, regardless how they defend them, Obamacare's Death Panels.
They are nihilistic card -carrying members of the culture of death. God gives life--they take it. It's not psychology--it's pure old-fashioned unadulterated sin!
Don't just blame liberals though--the GOP has more than its share of the same, those who hurl vicious curses at the social cons (God lovers) in their midst, as they, like Judas pursue their money gods.
