So your point is that if you were ever wrong or did wrong that means your opinion is forever void?
You keep bringing up op's past to berate him, make another thread if he's not suitably redeemed or apologetic enough for you.
I don't believe you've once offered any advice on how to change younger brothers c00n mindset which is also extremely dangerous.
We get it. You think op ain't shyt and you're better.
If you ever did wrong, don't expect people who witnessed your wrong doing to later view you as a moral compass or value your opinions.
I'm bringing up the Op's past because it's very relevant to why he's unable to communicate with his little brother, if the OP was someone his little brother respected and valued the opinions of, the situation wouldn't have escalated to the point that it did but given the OP's terrible past of gang banging, selling drugs and breaking into people's homes, the little brother has a difficult time putting any stock into what he has to say.
From the little brother's perspective, the OP is using white supremacy as a scapegoat because the little brother is smart enough to make basic comparisons:
My brother sold drugs and got into trouble with the law, I've never sold drugs and I've never had any trouble with the law and we both grew up in the exact same household.
In the little brother's mind, white supremacy doesn't even factor into that equation, it'd make more sense to attribute the difference between he and his brother to personal decisions and not white supremacy.
As far as advice goes, in my opinion, there's nothing the OP can do to change his brothers opinions, especially after hitting him because the OP couldn't control himself, thus reinforcing preconceived notions about people like his brother, people who solve problems with violence.
