Oh no! Not the RACIST CARD
AGAIN! 
Who gives a rat's arse.....? Lets get REAL!
If a certain hypothetical tribe consisted of nearly all fast runners, would it be racist to generalise and call them FAST RUNNERS? I think not.
Now, if another hypothetical tribe were nearly all ego-centrical, arrogant male chauvinists, would it be racist to generalise and call them L*b***s* (fill in the blanks)? Again, I think not!
For the record, I'm not a racist and want to save the planet so now I'm going outside to hug my tree!
