I suspect the hosannas to Muhammad Ali (who died yesterday, aged 74) will not include his views on inter-racial marriage. He was against it. At least at one time.
And no intelligent person wants to mix races, he firmly said during a speech in 1968.
And, he said in that speech, opposing miscegenation it isn’t a matter of hate. As he told Parkinson, it’s a matter of racial and cultural self-preservation.
What could be wrong with that? Nothing, if you are black or some other minority. It you’re white, it’s considered racism.
