Oh shit, Riker putting out the government name, he's serious now. I can't speak for everyone but personally I don't care what any new character does or is, but that doesn't mean I have to like or support every character change either.
I didn't say you have to like or support it. I'm asking why would the change be grounds for dislike.
I find it funny people get very worked up about straight white culture stealing their characters but then call any opposition when they do the same in return racist, how is it any different than those complaining about Scarlett Johannsen being cast for ghost in the Shell?
There are several things wrong with this here.
1. This is implies that Batman and Superman were created specifically to be "white culture," which isn't true. Characters like Batman and Superman weren't created to serve any purpose in ethnic culture, they were created to be universally appreciated and be entertained by. Hence why aspects of the characters change drastically throughout the years, including skin color(there have been black Supermen before).
2. The reason people are opposed to a character who was not originally white, male and straight being made into these things is that there is a history of systematic oppression meant to benefit white, straight, males. There has been a history of characters who aren't white, straight, males being underrepresented in the media, and when they are included, have been represented as archetypes, caricatures, or stereotypes, rather than with ingenuity, genuine, and realistic. The fact that white, straight males have nothing to gain from making a character into these things when they were not so originally because they have been massively represented in the media is why there's negative backlash when it happens.
Does being Japanese affect the character's story?
I wouldn't know, I haven't seen or read Ghost in The Shell, but the fact that they're casting a white woman in a role with a Japanese name is indeed stupid, and that can't be denied.
Character's shouldn't be so drastically changed and that goes for any race or orientation, would it be ok to make Staic white because being black doesn't actually affect his story
The keyword here is "drastic." Making Superman or Batman gay or black wouldn't be drastic changes their characters because what makes Batman Batman and what makes Superman Superman would still be intact if they were gay or black, or anything other than straight white males.
For example, Batman's character is defined by being a vigilante because he was was emotionally and mentally scarred by a particular trauma that has led to him developing a severe hero complex that drives him to protect the innocent and punish criminals and the "bad" by whatever means necessary while following a specific moral code.
Make Batman gay, and you lose none of that. Make Batman a woman, you lose none of that. Make Batman black, and you lose none of that. So any outrage against Batman being made any of those would be stupid.
As far as I'm aware, writers HAVE made being black a part of Static's character, using him to address issues of race, so yes, making Static white would be a drastic change in character.
