Are you suggesting that it's impossible to issue a warning, infraction, or ban without being rude?By that fallacious logic, every infraction warning, ban, etc for trolling would be ill befitting a moderator. Wrong.
As I recall, there was an occasion when I got dressed down for rudeness early on as a junior mod. Ainwood took exception to something I'd said in public, and told me it was inappropriate. I apologized to the member and took care to be more polite in future. I'm disappointed that some of the staff seem to think that their position excuses them from being courteous.
