This is a great narrative on colorism -- specifically, the stigmas surrounding whether or not somebody "passes" as White within their community of a specific BIPOC racial category to which they belong.
If someone is "White-passing," I wonder how much of that is due to a high concentration of Anglo/European lineage within their genetics from multiple grandparents. Plus there are differing perceptions of whether somebody is "White enough" to "pass" as a person of European descent.
Take someone with the complexion of Asa Soltan Rahmati from "Shahs of Sunset."
A Black person might take one look at her and conclude, "She's White" because her skin tone is much lighter than theirs.
By contrast, I would (being White), upon first glancing at her, assume she is Brown due to her complexion being much darker than mine...although to which BIPOC racial group she belongs wouldn't necessarily be so obvious, unless she was wearing traditional clothing or some other accompanying visual cue hinted at her familial heritage.
But nobody should be forced to wear their identity on their sleeve, if they don't wish to, for the benefit of anybody else.
