I'm biracial white mom/black father. Plenty of times during school life people said I "wasnt black enough", yes, even other black people, for a variety of reasons from liking to write and tk read a lot, esp horror stories by Lovecraft, King, Poe, and liking poetry Dickenson, Frost, etc, to judging me based on musical taste, liking rock music more so than the music they personally liked. It is a weird and stressful experience.
