If we can agree on 'knowing the difference between jokes and harrassment / mobbing' then I'm with you on this. It's all about context. 'Just a prank / joke' is too often an excuse for things that are actually worse.

the problem with that is lack of culture in the recipient, for example most of my peers would be very confused with the W word, ie. "Whitey" from Giles Scott Heron's "Whitey on the noon"...
