It's a black thing you just can't understand

I think what's really going on is discrimination (treatment or consideration of, or making a distinction in favor of or against, a person or thing based on the group, class, or category to which that person or thing belongs rather than on individual merit). I put up a definition because I'll hear a lot of people say, 'well, discrimination is a good thing and everyone does it. Their broad definition of discrimination (To make sensible decisions; judge wisely) is not what I'm talking about.

Racism comes in two parts.
One part is when a race feels superior to the other (reword: feels like another race is inferior in some way) and therefore has a right to dominate them or receive more privileges/rights than them.

The other part, and most important to me, is that a person's race determines their character, talents, abilities, personality.

The discrimination I'm talking about fits in with the second part of racism that I think is more important than the superiority factor. Actually believing a person's race is a determining factor in how they act, feel, speak, and even how they look, is what bothers me.

It gets tricky because people of all races feed into the lie. It's even harder dealing with a person of another race who believes the generalizaitions that are fed to them. When they believe that they are actually supposed to feel, act, believe, look a certain way different than others.

One black person is not the spokesperson for all black people. non-black people and especially, black people need to consider this when they speak on racial issues.

So, the idea that, 'you're not black so you can't ever understand or relate to what black people experience' is a bit of bollocks.

Now, I will say that history affects people in different ways. History has affected many black people in a way that is hard to relate to. Hard but not impossible. More importantly, history has not affected all black people the same way. We aren't all decendants of slaves and our predecessors weren't all in the thick of the civil rights movement.
All black people in America do not share the same culture.

It's true that many black people have had different life experiences than white people; but there is nothing inherent in their blackness that makes them experience life in a different way.

I think the 'you'll never understand' angle is a defense mechanism. I'd even call it a cope out because it says that you can't/don't feel like explaining your experience or you think the other person is too daft to understand. And honestly, it is kind of hard to explain sometimes.

I have noticed that I've heard it in conversations where a well-meaning white person who thinks they have it all figured out has said something that is completely ignorant. This tends to stir up some annoyance or outright anger in some black people and they counter with the 'you'll never understand' bit. Rather than educating that person they try to shut down the conversation with that phrase.
