It's been that way for ages. Criminal Minds was so predictable that "we're looking for a white male in his late 20s" became a meme among people who watched it, and that first aired 18 years ago. Comedians were making jokes about burglars in alarm company ads always being white as long as I can remember.

The only time a black guy has been allowed to be an unrepentant villain in any fiction for at least the past thirty years is when the main character is also black. Thanks to 9/11 we had a few years there when Arabs were allowed to be evil, but even then they always had a token peaceful Muslim who constantly delivered monologues about how Islam is a religion of peace and terrorists aren't true Scotsmen Muslims. When's the last time a white culture got that kind of respect from Hollywood? Oh, literally never? How curious.

Even bad batch made the Blue eyed Blond White commander as pure evil and incompetant

Exactly. I predicted this when they started this obsession. I love detective shows and stories but that’s also part of the reason I am very wary of watching anything made after 2014
