See this is another issue you have with communication: when you disagree with someone you can't simply speak authoritatively and tell 'em they're wrong.
Suppose you get stuck in some shitty corporate job in the future, and some asshole throws you under the bus blaming you for his or his team's mistakes. You can't simply stand up and say in a loud, chesty voice "THIS MAN HAS NO SWAY ON MY CHARACTER" before returning to your desk as if nothing happened.
My point was that to many others, the appearance is that you close threads when you don't like the direction they head. You simply retorting "no" doesn't refute that.
