I'd certainly be happy to change our admissions process such that it's purely meritocratic (but then remove legacy admissions, which mostly benefit white students). However, this idea that minorities need to "assimilate" into US culture is exactly the kind of racist nonsense that makes us decry the norms as whiteness. A lot of immigrants to the US face direct and indirect violence for things as simple as wearing a hijab. Having to present ourselves in a way that's comfortable for you all to not view us as a stereotype is taxing, especially when these efforts are aggregated as "anti white and anti asian hate"
Like what even is anti-white hate when less than a century ago Italians were considered nonwhite? "White" as a social construct only exists to contrast with ethnicities we view as lesser. We should not collapse 300 million Americans into 5 groups (none of which cover those from the middle east) and then base decisions off of such a subjective classification. It's obviously going to cause issues
