First I must say that McCOY is one of my favourites. Having said that , and remembering that it was 1960s standards, his racism is too overt.
How is insulting some one for thier pointy ears or green blood different from insulting them for skin colour. (Sorry for all the extra U's I am a Canadian)
At the time it was not seen as racist , but now his comments do make me cringe at times.
