Did he ever say that or are you just guessing that he thought that because he was strongly against mass immigration?
(I've read his infamous 1968 speech. There's nothing in that about superiority/inferiority of races. He believed that mass immigration would lead, inter alia, to civil strife. You do not have to believe one people is superior to another to believe that.)
I never really answered this question and it is a good question. I could probably scour the internet and find a quote saying that Powell believed he belonged to the master race. Also I could probably find quotes saying the opposite.
Prior to WW2, for people of Powell's class and generation, the idea of the superiority of the British and European white skinned 'races' was common sense. The empire was justified by this idea (and used as proof of it).
Hitler and WW2 made it difficult, politically, to express the idea in public.
By the 1960's the empire was gone, the commonwealth was born, and the western European economy was booming. Almost full employment, free love, free concerts, the Beatles - who needs to hate anyone?
I went to school in the 1960's and rarely saw an Asian or West Indian face. I haven't checked the immigration figures but would say, anecdotally, that immigration made very little to no impact on most parts of country.
Of course Powell was in Wolverhampton where there were actually some immigrants. They were not, however, a threat to anybodys job. In many industries there was a labour shortage. So what was Powell's speech about?
Powell was not a fascist. He was a parliamentarian. I do not think he was trying to provoke riots. I do think, however, that he believed the mixing of races to be unnatural (in the eyes of God?). There was no economic threat. He was a cabinet minister. He must have known that.
He uses the provocative example of the 'grinning pikaninies' persecuting the terrifed old white woman. It's an image that suggests the 'untamed savage'. It's certainly not an image selected at random.
This is not conclusive evidence, but I think his 'rivers of blood' imagery (in the 1960's - give me a break) is the product of an over-heated racist imagination. Maybe he was having sexual fantasies about his black housekeeper (pure speculation - no idea whether he had a housekeeper).
Anyway, JHE, that's my answer.
