> Disregarding genuine differences between cultures and intentially treating those cultures as identical is racist.

Just for the record, I don't think that's a widely used definition for "racism". Also, the linked article does not really support the view that he was "disregarding genuine differences"; if anything, his prejudice made him see differences where there were none (or misattribute traits that he notice on some individual to a whole population). The article speak about his contempt for the gaelic language though, which I guess is what annoys you the most? But then the article also states that he changed his mind on that.
