I have a sneaking suspicion that he may be exaggerating a little bit. My background in detective work (mostly watching CSI...) has kept me in close contact with legal resources that I just made up. This is from the 1979 edition of Exaggerated Expletives and their Function in Modern Society.
"Those who are incapable or unwilling to use at least rudimentary grammar, punctuation, and spelling, or to make an effort in that direction, have nothing important to say and should; therefore, be beaten about the face, head, and neck until such behavior ceases."
I rest my case.
