It's possible this guy is a jerk and that this company is a bunch of assholes. You don't minimize one party's guilt by pointing out the other party's guilt.

EDIT: plus, it's easy for me to avoid dealing with this guy. I won't be his friend. But I really worry about the culture of the software industry, and if Kixeye spreads to mean more asshole workplaces, that's something that's a lot harder to avoid.
