I had this epiphany earlier while typing up an angry response to a comment. It was long, and it was passionate, and ultimately, it would not have changed the other dude's mind. He would have replied to me, though, and I would have read his angry reply in my inbox. And I would have got even more mad, and the cycle would continue forever. The winning move is not to play. You just can't convince someone over the internet, arguing online is just self-gratification.
