wtf

What would motivate someone to send me an email like this, following up on a conversation about technical books in which I and others mentioned the widely revered book on the C language by Kernighan and Ritchie?

I quote the message in its entirety.

K & R Book sucks

it is bad

I mean, what??? Am I expected to respond "no, you suck"??? How can someone with the wit to know what K&R is have so little sense as to mail something like this??? I hope this is an outlier, but judging by some of my experiences teaching at Loyola, we are producing a generation of young adults that is salted by people with very little sense of what the world is or how to act in it.
