Don’t waste your time arguing with anyone whose opinion you don’t respect…

— Alex Green

“… This is doubly true when the person you’re dealing with is a zealot. (I define a zealot as someone who can’t change his mind and won’t change the subject.) You probably have better things to do than bang your head against the wall. Ideally, you want to converse with someone who knows more than you on a particular subject and can enlighten your point of view.“
