Being passionate is one thing. I've seen plenty of people who are equally passionate about their career, however, who are willing to admit they made mistakes, who are willing to learn from those mistakes, and who are willing to accept criticism. Being passionate does not excuse you from being an arrogant twit.
Now, I would not support the forming of a petition to end the guy's career, but he asked for it. Literally. That makes this totally acceptable. Whether he ends his career or not, maybe he'll learn to be more careful what he wishes for.
Unfortunately, I dislike giving out my e-mail address (not to mention my real name), so I won't be signing.
