Now, now...you may not like BMW's attitude or values or beliefs or morals or spelling, but keep in mind he's not from Pluto. He represents the opinions of a segment of society that's much bigger than you're probably comfortable believing exists.
I've seen it and heard it many times over the years. Worse yet, every time somebody starts spouting this line, there's always a few others saying, "Yeah" or, "Right on" and more recently, "Word, Dude".
So, he's doing you a service by warning what's out there to contend with, and more importantly desensitize you so won't be jailed for murder when you find it.
