Equality??

It's not that I agree with people like Georgie Zimmerman, but more that I don't understand the contradiction.  How can one man defending himself or whatever you want to call it from a black kid beating him be considered racist.  Fine...let's say he's racist and call it what it is.  How then is it that every story in which an older white man, or young white couple, or college student being beaten to death by a black person, usually a gang not considered racist? Or even considered at all?  For years black people have fought for equality and fairness.  Your ancestors fought for the right to vote and the right to be free.  Now that you have that you think it's acceptable to show racist hateful acts towards white people?  That is the part I don't get.  You want equality for all unless it's a white man who looked at a black man the wrong way, used the wrong tone, or said the wrong words.  You can call me a cracker and beat and kill people, but it's not even mentioned.  How does that make you any better than my ancestors.  It's doesn't...it makes you worse.  You know better and you've felt its effects, yet you force the same cruel  things you fight against for your people on to mine.
