Truth is a defense to slander. A personal attack is one which unfairly tarnishes the argument of someone by attacking their person instead of their argument; I fail to see where I've done that, since your comments speak directly to everything I've posted about you.
But I'll gladly retract each and every comment I've posted about you if you'll admit your smear of the Vatican was motivated by your bias against it, and not because of any support in the article here. Honest bigots actually have some value to the world.
