-you admitted to making your family look bad when you were in school getting suspended. Your brother hung his head in shame plenty of times
-you admitted to bangin, which could have put your family at risk
-you admitted to home invasions which could have landed you in prison or dead, and have your parents out here looking like they failed
but NOW you care about who's doing things to your family. Like I said before, you are the last person to be trying to "check" your brother. Let him learn on his own like you did. Nobody co-signin his c00n shyt, but you not the right person to be knocking nikkas out over blackness. Sorry, this is not the answer you wanted but this is what I see based on what you said.
