Hm, that analogy falls short for me. It's not so much exclusion (from whiteness, or from another marginalized coalition in the case of queer/trans stuff) that's the issue but theft/withholding/hoarding of resources. Racism and anti-immigrant sentiment in the US have overwhelmingly economic causes, mechanisms, and consequences. (On anti-Black racism, see "The Case for Reparations" by Coates; it's not long.) We don't undo it by letting more people into whiteness; instead, we decenter whiteness and end white supremacy.
