I hear you.
I think promoting self love/pride, etc is key. These mans are suicidal, which shows a level of depression, and other mental health issues. Like kids being 16 and rolling with a dipper and actively saying they don't care if they die. That's not gang life, that's a mental health issue.
Multiple reasons why they get like that, lack of family structure (look at the large majority of these kids who kill or get killed - they only show the mother mourning), lack of well established black role models in the ends and in media (most of these mans look up to rappers, trappers, etc), the schools are a shambles, where most schools only care about staying afloat rather than actually teaching something the kids want to know about, the list goes on.
Also, the media in this country are a fukking joke. That white girl got killed by a white guy, and ALL the attention is on her, showing her caring pictures outside Downing Street. But if it was a black kid who murdered her..lawwwwd have mercy. They would have had his history from when he was born, gang-style pictures, says how he likes grime/trap/drill, all splattered over the TV.
But anyway. RIP to all that died and hope for all those who want to kill
