Absolutely! Biracial and multi-racial people experience racism from all sorts of people who don't like some aspect of their lineage, and sometimes they endure a sort of punishment for being light-skinned. Being forced to associate with a side is the topic we don't grapple with often, and it's unfair to those people. It's a topic we don't discuss enough.
When it comes to race and anti-Blackness, biracial people do what's best for them. I have the most respect for biracial and multiracial people who claim their race as Black. Blackness comes with so many bags to unpack. It's easy to deny Blackness and anytimes its done, the Black delegation always knows why. It's quite the dilemma to be in.
