Interesting notion: they do it because they hate! Maybe hate is the operative emotion, growing out of caring and morphing into hate..Gun control advocates put forth "heartfelt" and emotion-driven ideas, then they hate and double-down against those who question their ideas. Why do radical Muslims hate non-muslims and "moderate Muslims?" because moderates and infidels do not follow the teachings they glean from the Koran. The parallel is not exact but close enough to think about.
