Its not a debatable point either..

"Hey there aren't enough blacks doing this thing!"

"Oh really? A lack of blacks doesn't appear to be causing problems. Why do there have to be any, what is an appropriate number?"

"Er.. infinite diversity is the ideal!"

"So only blacks can do this thing? Like being africa is ideal to you? It looks totally shit to me there buddy.. that's why people are fleeing there to come to here."

Its just thievery with a moral facade. 'Let them do these things!!' very quickly becomes 'You have to fund them to do these things!!'
