I do not agree with everything this man says in his video or on his channel but I admit to finding it jarring to see black actors portraying figures from European history & legend whose skin colour was not black and for whose contextually anomalous ethnicity no account is given. I doubt this growing phenomenon is planned in any way but with time the effect on younger generations will be the same as though it were, a Whiggish rewrite of history in which current liberal values around culture are seen as eternal and from which all taint of racism is scrubbed. Racism was historically & politically inevitable when ethically & culturally different populations began to meet, which is not to say that it is something we should preserve or should constantly rehearse in our drama, but young people need to understand that up to now cultures the world over have historically been almost exclusively politically ethnocentric and in population ethnically homogeneous, often in conflict with one another rather than with orcs & ogres or some other fantasy enemy, yet still have managed to achieve great things and move beyond their prejudices. As adults we have had the benefit of an education largely unaugmented by broadcast & social media so we are unaffected by exotic casting choices, but our pupils swim in this stuff and, like fish in water, have no reason to wonder at it. Is it fair to allow them, regardless of their ethnicity, to believe that our historic & legendary forebears lived in a multicultural golden age?
