Okay kiddo, so have you ever heard of the word "race"? It's a way that people categorize themselves and others based on physical characteristics like the color of their skin or the shape of their eyes. But did you know that some people believe that race is more about how you are treated by society than about what you look like?
That's where the idea of political blackness comes in. It's a term that some people use to describe a political identity that is based on how much discrimination and oppression someone faces rather than their actual race. So even if you don't have dark skin or other features that are usually associated with being "black," you can still identify as politically black if you feel like you are being treated unfairly because of your race.
This term became popular in the UK in the 1970s when people of different races and nationalities came together to fight against racism and discrimination. They realized that they had a lot in common even if they didn't look alike, and they decided to unite under the banner of political blackness.
Now, some people think that using the term "black" in this way is confusing or even offensive, but others believe that it's an important way to show solidarity and create a sense of community among people who are all fighting against the same kind of discrimination.
So there you have it, kiddo – political blackness is about identifying with a political group based on the discrimination and oppression you face rather than your actual physical appearance.
