OK, let's be real.
What is the effect of years of anti-Muslim bigotry being spewed, screaming about "sharia law is taking over!" and "they won't stop until every Christian is dead!" and every other ignorant statement puked up by Pam Geller and her ilk?
A blond Norwegian Christian kills other Norwegian non-Muslims on the theory that he was fighting a war against the encroachment of Islam.
But that was an easy one, right?
OK, then. What is the effect of years of people shouting "baby killer!" and "abortion is murder!" and trying to defund or destroy Planned Parenthood at every opportunity?
Some toothless inbreeder tries to firebomb a Planned Parenthood clinic, apparently not aware that diesel fuel is a terrible accelerant, as it does not explode and has a flashpoint of 143°F. Which is why he caused minimal damage.
Oh, and diesel is currently more expensive than gasoline.
Oh, and one more thing: that particular Planned Parenthood clinic didn't perform abortions!
One wonders how humanity manages to survive, when they seem to be racing headlong back toward the feces-flinging stage.
