What he is saying is completely correct on the context that he is talking about the people insisting on pacific resistance to Fascism before WWII.
The person quoting him without context in a way that completely changes the meaning of his words is wrong, and one has to wonder if honest at all.
He is smarter than people, has perfect emotional control, and a complete psychopathic detachment from anybody's else well being. And yes, he's more physically capable than people in every way.
I guess the reason he isn't used very much on the series is because otherwise the authors would have to let him destroy the Federation,
