NA server story

TvT in the 50 practice league. I rushed his base with my 5 banshee, alternating between his main and expension. Mainly for practicing micro. His built was solid, there is huge MMM. i fly around and takes out all his tanks in case of counter attack.

Transition into Thor with scv. When i was moving out he suddenly came from behind crushing my armies and he won. Then he starts swearing

him :!#@$ you
him : noob!! !@# you
him : i am diamond player
me : no way
him: i am, check out ***** id go check now, !@$# you
me : you are mad of my banshee attack? Oo
him : yes @#$# you! banshee is for wussie
me : you are not diamond

in the end due to my nice manners ^^ we became friend and rematch and i lost, his other id is indeed diamond rank top 20, all he knows is MMM.
His strong point is good macro but that is all about him =.=

wtf diamond players in NA raging over banshee assult?
