I attack with laughter and sarcasm. Other people have different coping mechanisms. Mine just happens to be socially acceptable atm. It wasn’t always, such as in school where I was accused of not taking things seriously.
His derisive "Congrats!?" would already be in violation of modern American corporate communication guidelines and policies. That sarcastic praise made me feel belittled. The exclamation mark made me feel threatened and unsafe. Failing to coddle me is aggression.
“Jesus Christ, if you could just explain why then we could have a fucking discussion, yeah?”
Intuitively you already understand the point I am making :)
