While I think this is a great discussion, I also believe the issue is being over-complicated. The gentleman who wrote you is insecure (arrogance and/or pride is always the result of insecurity), that insecurity has bred jealousy...and his jealousy resulted in demeaning behavior. His tweet says a lot about him, and your response says a lot about you. I don't know either of you personally, but Erin, I know who I'd rather be led by.

Love your spirit, your humility, your selflessness, and your drive. Keep up the great work!
