Don't be a douche, obviously I don't think it's the same hence my comment. And I'm willing to bet, same as you, my source was Google to verify my memory of something I read long ago.
I didn't name call, saying don't be something isn't remotely the same as saying you are something. If someone tells you don't be a jerk, they're not calling you a jerk, they're warning you you're nearing that point. We're done, good will has exited the building, there's no point in continuing.
