it's better to have there both white, black and Asian people because kids wouldn't become racist.

No, it's not, it's better for people to be able to have media that's meant for them. And when people shoe-horn in non-euros it's called appropriation, and it's a bad thing.

It's not appropriate for a euro kid to feel like it's not ok for them to relate to and like euro stuff for euro people. Nobody ever does this with media for anyone but euro people. Nobody's going to a syangogue and talking about how we need to insert Aboriginal Australians into the story of Moses in every and all contexts that little Jewish kids here about it so that they won't be -ist against them. Nobody's talking about how it's a problem that African media doesn't not only include but center Saami people and influence in any and all stories they tell about themselves so they won't become -ist against them. Or how Koi-San people need to always be included in tellings of Inuit traditional stories in all contexts. Or why it's wrong for Aboriginal Australians to tell their tales without centering the influence of Lesbians (actual Lesbians, from the mediterranean island) in their history.

I think it's wrong when people do this, and I'm angry looking back at how this was done. At the time, yes, I believed it was a positive thing as stated, but it's increasingly difficult to believe that now with how blatant it's become. Things are celebrated for lacking white people now, even when they center white history! Wakanda was a story about European technology. Look up who Obama chose to do his presidential portrait. I had been so happy when he was elected!

Racist isn't a real concept, it's a political weapon. It's just a concept made to stigmatize white ethnocentrism, that's how it's always functioned. Is anyone seriously trying to do anything about ethnocentrism or ethnic pride in any other group? Latino celebration rather conspicuously tends to avoid celebrating and explicitly connecting to its European half, surely that's a problem? And African American culture certainly isn't taught to value the contributions of Europeans to their development. Nor are Amerindians, whose image is largely associated with something that came to them from Europe -- the horse. Ethnocentrism is a normal, healthy, and necessary impulse and doesn't at all preclude international friendship, alliances, cooperation -- rather the opposite -- good fences make good neighbors, and all that.

Euros are objectively one of the least ethnocentric people on the entire planet. If you want to work on it, I'd suggest starting with Jews. They are among the most. We need to stop telling Jewish stories that don't center non-Jews, because Jews do objectively often think they're better as seen in polls and stuff. If they follow their religion, they dehumanize others as their religion tells them to. If one thinks making judgements about groups in that way is a problem, that is a far more urgent issue.

Or don't pick Jewish culture, whatever, I just get irked with Jewish people doing this kind of thing because of the hypocrisy. And they are one of the most ethnocentric groups. I don't know anything about you, maybe you're a big protestor of Israel or something, I mean in the general context we're all existing in right now. Literally any other group but euros is in bigger need of this alteration to their stories.
