The only reason for employing some one should be based on their merit and ability to do the job, it should be a business decision not a political or social one etc. Likewise you should not employ some one just because of their race, sex or some other lefty reason.
True - however I can't help thinking back to what my now-deceased mum said during discussions with the family on how best to have her looked after when she became unable to live by herself. One option put forward was to have an either live-in or visiting carer - mum was adamant that that would only be acceptable if the carer wasn't "a blackie". She was in her late 80s, had fixed views that she wouldn't change (wouldn't or couldn't explain them either, and had never voiced them previously), so we dropped that idea for fear of both upsetting her and upsetting the Employment Law nazis....
She ended up in a rather expensive nursing home - where she did have a disturbing encounter with a coloured nurse, ringing me at 2:00am screaming that there was 'a blackie had come in to her room to get her'. Both nurse and nursing home were very understanding & simply re-arranged rosters so that it didn't happen again
