The point of a microaggression is that it's part of the constant pressure of not being part of the "dominant race". You can't do a microaggression to a white person because there's no hierarchy where you're above them to reassert.

The problem with Nguyen is that while among white people, it's an uncommon name, among other populations it's INCREDIBLY COMMON, which isn't common knowledge. I think this a pretty negligible example though. Nowhere near as egregious as wondering if people are related because they're just the same race.

Hierarchy I don't believe is the right term. The homogeniety of norms is what matter. White women have surely encountered microaggressions. Non-normative white men as well. Honestly everybody differs from the norm in some way. The magnitude and frequency are what make it matter.

Someone thinking your last name implies kinship is whatever. Someone thinking you're a secretary because you're a black woman when you're the CEO is a big big problem.

This is false. The white person may be a member of an ethnicity seen as non-dominant. For example, his surname is unusual because it is typical of Muslim peoples but not for historically Christian whites, as for many immigrants to the USA from the former Yugoslavia or Albania. Yet unless the person asking about the surname is intentionally targeting that ethnicity, the behavior cannot reasonably be called anti-Muslim racism, let alone used as proof of a rising incidence of what is specifically termed "hate".
