That comes across as pretty condescending. It's not like you have some sort of authoritative high ground about what does and doesn't constitute professionalism in the business world. It sounds to me that your version of professionalism is in line with what gets prescribed at your average mindless corporate human resources or public relations department. Which is fine, but there's zero proof that that is the correct way to do things, and it's actually naive on _your_ part to accept the status quo as is. And, as I said, incredibly condescending to assume it is somehow the "mature" point of view.
