Britain is 3% black, if anything in recent years there is a massive over-representation in TV shows and adverts in the UK, even when something is set in a tiny village. Unless it is set in London, then they are probably underrepresented (see Eastenders for an example).
I don't know, maybe it is because I am comfortable in myself that I don't need a TV show to validate me and I am quite comfortable and able to watch a TV show without seeing myself 'represented'.
I don't watch The Fresh Prince of Bel-Air, Luther or Luke Cage because I want to see myself, I want to be entertained. The same reason why I also like shows like Gilmore Girls, Buffy the Vampire Slayer and Veronica Mars. I don't need shows to always have a male hero, but I guess I don't suffer from the need for constant validation.
The problem with TV the last 5 years is that entertainment has become secondary to the messaging. No-one made a huge fuss back in 1988 when two of the three main characters in Red Dwarf were black, or when Avery Brooks became the first black headliner of a Star Trek show (maybe they did, but I didn't notice), it all just seemed perfectly natural to me. Nowadays people have to make a huge deal about it, like it is something new, and the Twitterati are all out clapping like demented seals! Same as they do whenever Jodie Whittaker and Yazmin in the current series have a 'Thasmin' moment. Doctor Who is not written for everybody any more, under Chibnall it pandered to the woke progressives.
I am hoping under RTD that Doctor Who will get back to entertaining people, and I hope that Ncuti is a dynamic Doctor who stays away from romantic entanglements in the TARDIS.
And as for the term 'cis-gendered white male'? I don't know anyone who can take a term like that seriously as it highlights the obsession with race the far-left has, having to categorize all groups and put them in their little boxes. Most people are not that political and treat people as they find them, we can already see the woke types bitching that if Doctor Who does not succeed it will be because of 'racism' etc, even though a small number of fans are that way inclined. Most of the progressive types who are championing Ncuti's casting won't even watch the show. It is why, when you pander, rather than entertain, the ratings end up in the toilet. Progressives complain about TV shows, but they seldom support them.
I have a good feeling about Ncuti, especially with Russell's writing. Chibnall's era felt like a total box-ticking exercise and almost every episode felt like a lecture. When I watched an episode of Tennant recently (Partners in Crime) and Smith (The Eleventh Hour), boy, did those episodes seem incredible when compared to recent stuff. Jodie's first episode by comparison was awful.
