This is a very difficult question.
We as a blog have decided to center queer Latinidad on the most marginalized among us (undocumented, trans*, women, black, indigenous, non-monosexual, non-binary, gender nonconforming, femme identified, and everyone at the intersections of all these axes of oppression.)
That said, when addressing racism, we will always center the conversation on those who cannot (under no circumstance) ever be racialized as white.
So are white Latin@s POC? Short answer: No. BUT Long answer: Sometimes.
White, white-passing, and light-skinned Latin@s walk the world with the privilege to (under most circumstances) avoid anti-black and anti-indigenous racism. This does not mean, however, they do not experience discrimination based on their culture, language, surname, etc.
Sin embargo, this is NOT racism — necessarily. In most cases, it’s xenophobia and anglocentrism that intersects with indirect racism.
However, we are very hesitant to identity police. If you are a light-skinned/white/white passing Latin@, you can identify as a person of color. BUT — and this is IMPORTANTÍSIMO — you need to realize that you take up space in ways that black and indigenous Latin@s cannot.
You can see yourself in Latin@ media with greater ease. You are considered more beautiful than your darker peers. You will be hired for a job before your indigenous/black Latin@ peers. This is the truth.
Being a white Latin@ therefore gives you two options: contribute to marginalization of your herman@s who are not white, or use your privilege to challenge it.
The choice is ultimately up to you.
