"Really" Black

Can someone please explain to me what the hell that means? I mean, to be considered black, do I have to speak a certain way? Maybe dress a certain way? Have a certain IQ? Are there all these little standards that I have to meet so that I can be called black? Just recently, someone thought I was only part black BECAUSE I AM SMART. REALLY though? How much more ignorant and narrow-minded could you get? At least that whole "acting black" bullshit has some foundation, but to say that I'm not 100% black because I am smart is some of the biggest bullshit I have heard in my life. It actually kind of makes me sad. That someone was REALLY that ignorant. He's very lucky he didn't say that to my face. I don't know what I would have said. 

But I don't get it. Do I really have to act a certain way so that I can be called black? I mean, how come I have to conform to some ugly stereotype to be considered my race? I mean, with white people, even if they act ghetto, they're still called white, right? But with blacks, they have to act a certain way so that they can be called really black? And how the hell does not acting a certain way disqualify me for being considered black? So are you trying to tell me that I fell into a vat of paint or something? And that it never washed off? Being black isn't determined by how I act, it's who I am. I'm sorry that I find it acceptable that I talk with somewhat proper grammar; I just don't see why I should lower my level of speech so that I fit in. I'm sorry that I like to dress the way I do because it's what I like. And I'm sorry that I find it ridiculous that some people wear belts and then put their pants at their knees. How does that make ANY sense? It's stupid - if I'm going to wear a belt, I'll wear my pants at my waist thank you. 

And I find it kind of sad that most blacks act the way they do. It's sad that I'm considered an outsider among blacks because I don't choose to act out and cause a ruckus. No matter what I say,what I do, how I dress, there is no one who could really convince me that I'm not really black.
