Why can I not use the word Black for people, and yet a woman can use the word cock and *** to mock my question?

I am here to give a gentle rant! In America we have given the country to our "Black" compatriots. They can call us "White, and others Mexicans," but we are censored for using the word "Black," even when it is used respectfully. I say everything is the governments fault, they have given America away to those who scream loudest and to the wealthy. Forget those who struggle to make rent and feed their families! And now if I say one negative word about Obama, I am criticized. But when I speak negatively about McCain, nothing happens. What the fk is happening to America. Their are many good and even great Black Americans, just as there are many good and great Americans of every shade and tone of color. I say that the government needs to stop categorizing our fellow Americans and that well eventually create a change of one America, united as one people!
