With that said, I'll play the game. What about now? Is he still so scared of them that he feels like he still needs to represent them, or needs them for protection?
When is it time for him to grow up? Gangs don't help society, they break them down. There's a reason why when gangs move in, crime rates go way up. Does it automatically mean your a criminal? No, not 100% of the time, but 99% of it does. Don't act like the Bloods are a bunch of school boys handing out in the local park.
They're funded by illegal activity, they push drugs/guns, they steal, they rob and murder people. You don't go through that lifestyle and come out squeaky clean.
By still showing his colors he's supporting the lifestyle, that's why they feel like they don't have a choice, because the adults kids idolize don't show them they have a choice. They glamorize gang life.
So what he started a school, good for him. How many kids does he help compare to how many kids he hinder? He should want them to get out of the streets, create a functioning life in society. Not be apart of the scum, which is exactly what gangs are.
