What strikes me about this exchange is that the comment wasn't directed at a fellow team member, an alliance partner, a parent, a sponsor - it was directed at AN FTA. The single most critical position at any event. Without an FTA, an event just plain won't run (assuming the use of official FRC equipment). The manuals give the FTA complete and final authority. This individual should be treated with utmost respect in any situation, reagardless of situation or circumstance.
I can't speak on behalf of other teams, but in our team, I don't tell the students they have to be respectful. I DON'T HAVE TO.

If I have a student that, after a fall semester and entire build season, I have reservations about that student representing our school and team well while at an event, I have no problem un-inviting that student to the event. Competitions are a reward for months of hard work; if a student cannot behave during those three days, that student should not be there.

I can't count the number of times I've seen the reprimand on CD of "no matter what the disclaimer, you're always representing your team." Doesn't this extend beyond the interwebs and into competition?
