Valkyrie feels discriminated against.

Have you ever thought about characters not being stand-ins for a folk but as individuals? 

I doubt she is meant to be that, her name is based on norse mythology and that should have told you that.

A character having an uncommon haircut isn't racism. A German looking great with long and fabulous hair isn't common here, but thats because most people haven't seen me yet and it still wouldn't be racist if we'd get a german with great long hair.

Also her having no kimono is not a problem with the character, there is no lack of cowboy hats and absend father figure for Bangalore and no lack of sombreros for Octane (or maybe there is depending on your sense of humor) and that character almost embodies everything that Joe Biden and the MAGA boys think about latinos.
