There is a counter-argument to this though. You mention stop and search, but what about the grooming gangs in various northern towns that got away with their despicable activities for longer than they should, due to the Police (and other agencies) not wanting to be seen to be racist?
What about if an employer picks a BAME candidate over a white person, so their company has a more diverse staff, when in fact the white person may have been the better candidate?
Recently, a black comedian was a last minute sub on a Radio 4 News Quiz programme because the BBC realised that its original line-up (4 white guys) was not diverse enough.
Is that not just political correctness gone mad? Think about it from the guy who got sidelineds point of view - it might have been a life changing/career changing opportunity for him (if he'd been funny on the show) but he was denied the chance & for this reason!!!!
