Awesome post! Thank you for speaking from a place of honesty and vulnerability. I just wanted to comment on this --"White identity is by nature exclusionary, and being mixed invalidates my claim to whiteness." This is a very U.S.-centric view --in certain Latin American countries, you would be considered white based on being mixed. The racial algorithm in the U.S. is based on hypodescent, but elsewhere it can be hyper-descent.
