Well I'm afraid that in the real world people form judgements based upon firm evidence, not from their limited personal scope.No, I'm talking about things from experiences of people I know ... studies rarely can give an accurate picture of things like this because for a study they would probably say "there are fewer black police people than the percentage of blacks in Britain, therefore the police must be racist" ..
Citing yours and your acquaintances limited personal experience as evidence that "Racism as a whole within large organisations has fallen to almost not existent levels really" isn't good enough.
