Sorry but I have to break this down
Fine cool. (Just note Most popular character was created in era that was racist, The comics creators weren't racist themselves but they couldn't make diverse books who would buy them? Anyways superhero comics revolve around this period characters which is fine but when it is time for books to refocus they always default to these characters aka X-men,Avengers and Justice League get diverse as hell but when it is time to refresh concepts the books always end up very very white.)
Once again fine. Basically you are saying I don't care that all old popular characters are white, You grew up liking them because they were cool and every comic book fan understand this but you never had a choice
Here is where your argument breaks down, clearly characters are defined by their representation because changing clearly makes a difference to you.
So to be clear your first two statement says hey keep characters mostly white and not reflect the real world. Your third statement is don't old characters to other races to more accurately reflect the real world like they would if they weren't created in that period. Finally you don't people to complain the fact comics aren't very diverse in terms of the major characters and you don't want them to express that opinion. And it is last statement that is most annoying because you want people to be stuck in past like you. But to each their own.
I don't get it, personally I love comics I am not going to stop reading them because the characters don't look like me BUT why shouldn't some look like me? Better yet why shouldn't characters that matter in the story look like me? Nobody wants them to change Superman or Spiderman to another race BUT where are characters from other races who have the impact of those guys. Yeah that right Two big is consistently push older characters as important(we can discuss why later). I have been reading comics for nearly 30 years now. That how long it has taken for 1 character to break through in Black Panther as big time character main stream and two characters to get shows in Black Lighting and Luke Cage. Yes I am well aware Blade(who hasn't shown up since) , Spawn(who hasn't shown up since),Static( who hasn't shown up since).
Anyways the big point you don't care fine that is on you but why are YOU against other people being able to see themselves when they look at heroes. Name me ONE Asian or Latino hero that has been in Marvel or DC film. We are in 2019 freaking Katana and El Diablo will probably be your answer. You might not care but would it be nice to have ONE ? Just ONE significant well made minority character that looks like you but hey just shut up and say nothing I am sure they will create one. Right? Justice League fails does horrible but Batman still gets a movie, Wonder Woman of course gets a movie, Aquaman still gets a movie, Flash which keep losing directors and script is up in the air is still gets a movie. Cyborg though disappears off the face of planet. Yup that is problem in the nutshell. Cyborg doesn't get a movie but Batman does but you still want to see diversity hmmmm. I guess we have might change Superman or Batman to another race. Final point yeah it is not big deal but how does saying nothing make things better?
