What Powell said on the matter of racism is well documented. Since you are young I will take the time to post it again here which is the recorded exchange featuring David Frost and Enoch Powell in 1969 or thereabouts:
David Frost: " A lot of people say you are a racialist: will you admit to being this."
"It depends on what you mean by the word 'racialist'. If you mean being conscious of the differences between men and nations, and from that, races, then we are all racialists.
However, if you mean a man who believes that one race is inherently superior to another, then the answer is emphatically NO."
