Diseases in example sentence
No-one is saying that the English did not do terrible things when they settled the American continent, but to suggest that the natives lived in some kind of paradisical bliss is equally absurd; moreover, the film supplements this simplification with a dangerously inaccurate implication, namely that the only good Englishmen were the ones who settled America! (bizarrely, the bad Englishmen kill all the natives with their diseases, while the Pilgrim Fathers live happily and healthily beside them).
