I have looked at the "appropriation" controversy with an increasingly uneasy feeling about its ultimate outcome. You would think that what the Walrus would want is the best, most competent, most visionary person for the job. But we are told that the most politically correct candidate wouldn't be a man and wouldn't be white, and maybe wouldn't be straight. What that will mean is that losing white, male, straight candidates can with justice feel the game was rigged against them. Can, with justice, feel that same rigging will likely be going on in other areas as well. I would suggest that if there is something that you absolutely don't want to copy from the U.S., it is a public policy which says that all straight white men have been over-privileged and accordingly should today experience discrimination and prejudice in the workplace.  
It is an approach which if adopted will lead to - as it has in Trump's America - something which might be called revenge politics.
