you can always offend the professional offendees. iirc the big bruha over Sachsgate was after a repeat airing. someone had written about it in a newpaper and upon the repeat hundreds of compalints were made, versus none for the original. though i maybe confusing with another incident...
an asian colleauge used "coloured" recently and i did mock offended "you cant say that" and they looked at me blankly. i explained and they just rolled their eyes "cant say anything can you". its daft, the rules are being made up as we go along.
