One of the best examples of [color=006600]ignorant, offended, cerebrally-challenged[/color] persons, was related by a Maths Major when this story broke on /.
It seems that a group was exiting from a Maths exam into the passageway. The story-relator turned, and said to his companions- "H##, I hate [color=660000]intergrating[/color]!"
A strident female blocked the group in the passage and pointed her finger at the speaker. She publicly (and loudly) condemmed him for what she perceived as an unwillingness to refrain from racial-discrimination!
Since most in that passageway were in mathematics, she received laughter from ALL sides.
(Intergrating is a mathematical operation)
