This is called reverse racism.
YC's doing a great thing here to support and foster underrepresented groups in the startup founder world. Being from an underrepresented group makes so many things harder because as a founder raising capital it, unfortunately, is often more about what you look like and who you know than your product or your vision.
You're wrong, this is exactly what reverse racism is:
Next time you experience racism in the real world, saying something - experience first hand what it's like in the real world to confront it, then reflect on why it's wrong to make choices based on race.
