As for white male villians, well what do you want Lex to be something else than white? Or Otis (who was white in the Chris Reeves films) And like it or not there has been only one black president, so a male president would most likely be white and most college professors are white.
So after black vikings, black Asgardians, black Iron Man, black SpiderMan, black companions in Robin Hood, black neo-Alfred in Batwoman, black James Olsen... now black evil Lex Luthor or black evil US president don't make sense. Because, well, there has only been a black president in modern times. It's not like black vikings, that were very common.
Of course XDDDDDDDDDDDDD
Loving the shout out to the Black Viking trope but is anyone really complaining that Idris Elba was Heimdall, hell does anyone complain about Idris Elba in anything.
Hell its Idris Elba....which is very nice to think about in any sense.
Black Iron man - you mean Ironheart? That is a different character not a black Tony Stark
Black Spiderman - again a different character. Not simply a black Peter Parker.
the character in Batwoman (I can't stand Ruby Rose) is supposed to be linked to Lucas Fox, not Alfred
Black Jimmy Olsen - a lot better than the Zack Synder Jimmy Olsen
Black companions for Robin Hood - they are supposed to be Moors, which is at least a reason for being black in England at that point, rather than just have them without any excuse like they were born in Nottingham at that time and Jamie Foxx should give back his Oscar for that last movie.
Now black Lex Luthor? We have a white mother and Lena being the half sister through their father, so a black Lex wasn't going to happen. But why Black? Why not Asian or Hispanic?
A black evil president - yeah possible but roll the dice and look at the stats. More likely the President will be a white male seeing how we've only had one out of 45 not fit that mold. Or are you against the stats now??
So black vikings are OK. Black moors in XIIth century England is OK. And so. But a evil black president is wrong because black presidents are against the stats.
You, sir, you're a racist. You'd even be a racist in XIXth century: back then, you didn't see evil characters being played by non-white actors in the stage.
Don't you know what the black Viking trope is? Look it up.
And how can you complain about Idris Elba????
And you didn't see non black actors play evil parts in the 19th century? I wasn't there so I don't know. Probably not a lot in Europe and North America. More black face if required.
But in Asia and Africa there would have been a lot of non white good and bad guys I'm guessing.
And to be honest there has been a lot more white straight males playing president than not, have been president than not. So law of averages - you have a white male playing the US President.
