You have people literally defending uncommented, unclear code in your replies.

There are phases programmers go through. One phase occurs about after 10 years of professional programming. I call this the "no mercy" phase, where these newly-minted senior programmers think defensive programming is for noobs, and scrunch their C code down to the fewest number of lines and characters. And when someone objects, the reply is, paraphrased (as seen in the replies): "You're just not as good a programmer as me." Sadly, it takes another 10 years for this arrogance to dissipate.
