"Deliberate insult" would describe the original posting more accurately.
Whether you prefer to look at it as a show of bad manners or as trolling
is a matter of perspective; arguably it had been both.

Request duly noted and denied.  For the record: condescending twits of that
variety ("I can't be arsed to look at code I'm commenting on; here's my
valuable insight that is obviously beyond the mental capacity of anybody
here") can expect a harsh reply, whoever they are.  I'm yet to see l-k
regulars treating newbies that way, BTW, despite the much decried lack of
politeness.

Since you are postulating social norms, here's one you seem to have overlooked:
one who comments on code or design, be it review, suggestions of changes/
improvements, etc., ought to read the thing he is commenting on.  Whoever
it is and wherever the code in question might be.  And yes, it applies to
kernel hackers commenting on newbies' patches to the same extent as to
completely unknown folks commenting on the kernel, etc.

Breaking that rule and being caught at that is one hell of a way to earn
yourself a lousy reputation.  Combine that with arrogance and... well,
there's a term for what you become: target practice.
