Didnt they originally say Kang will be played by someone else? And if not, wow thats 1.
Also you guys need to stop calling He Who Remains Kang. Hes not. Hes nathaniel Richards. Kang is alternate variants of him. Kang has yet to even show up in the MCU.
Black lady in Loki? She works for the TVA and protects time. Just because shes chasing variants doesnt make a villian. You can be an adversary without being a villian. Was Ironman the villian of Civil War?
I think you have a point here overall. Almost all of the villains in the MCU have been white men. Rewatch Star Wars Episode 8 (or...don't) and it jumps off the screen how the Resistance is composed of a very diverse mix of people with like one (fat) white man in their ranks, while the bad guys are 100% white men. I think the one fat guy gets blown up too, and has a very minor role. I brought this up at the time and was assured that "well, the First Order are nazis so they only employ white men" and it's like...yo, Finn was one of them like one movie ago.
Regardless, you have a point here. To try and debunk your point we have to get into the weeds of what constitutes a villain or not. The black lady in Loki isn't a villain, she's just a TVA agent doing her job. And literally every non-white-man villain in the MCU has quickly turned out to mean well and join the heroes. Adversary doesn't mean villain, like you said. There have been a bunch of
adversaries who were non-white-men over the MCU but I challenge anyone to name a single one who was actually evil or irredeemable like most of the main villains have been. The only possible answer I can think of is Killmonger and he was, as you said, given an out with his backstory explaining why he was the way he was and how his goals were on some level actually noble in their own way. Edit: Oh yeah, and Mordo. I guess there's that one.
Kang the Conqueror would be the first really vicious/dangerous/evil non-white-man antagonist in the MCU...and I'm pretty sure he'll just end up being blue anyway.
It might not be high on my list of concerns, but people who point these things out aren't exactly wrong. It's framing things a certain way for a mass audience and I'm not sure if their motivations are entirely altruistic, as opposed to the pushing of a certain undermining ideology that's been making the rounds.
