"Send an e-mail in all UPPER-CASE. Use of upper-case words is the equivalent of shouting in some one's ear. ONLY use upper-case words when trying to make a point (such as I just did). Even at that, you should be careful with who you are exchanging messages"

Here is a guy twice shouting and telling you at the same time that it is wrong.

ONLY use upper-case words when trying to make a point.
ONLY (SHOUT IN SOMEONE'S EAR) when trying to make a point.

Is this not encouraging shouting or am i misinterpreting what he said.
