Debian is a volunteer organisation. And although it hurts to admit it, there will be people who do not present professionally. I do my part, and I try to look mildly professional in what I do, but not everyone does. Thats fine - you cannot force things like that apon volunteers.
This is the same kind of issue as I saw crop up on policy/vote earlier.. which was withdrawn.. again, the people who do all the work are volunteers. If they were paid, they would have to act responsibly, but they arent, and you have to take a bit of the bad with that as well.
