How one is raised means a lot, but white children generally don’t have the racial chip on their shoulder that blacks are encouraged to have. They (whites) tend not to run in packs and attack blacks for example.
Today they don’t, but not too long ago they did. In the 1920s to 1950s, white youth gangs were common, and just as vicious, even though not particularly motivated by race, except in inter-gang rivalries with other ethnic gangs.
Today gangs are seen with two models. One is the ‘hood model, which is the more traditional gang pattern. But the more recent one, which is racism based, is the “wilding” model.
Such gangs are at least in part ad hoc, a small mob forming
then moving rapidly in a single direction through an area or a public event, far away from their ‘hood, attacking those they meet, or ravaging a single store, for example. If confronted, they do not fight back, but scatter.
They are opportunistic, with one say punching or hitting a victim from behind. If they are not knocked out, the group just continues to move, but if they are, several of the group will converge on them to beat them savagely then rob them.
