Interesting; for what it's worth, as a black person who grew up in a relatively privileged environment, the "one bad fight" rule was subconsciously our entire existence in a way that it wasn't for many people around us.
More likely to get hit with a Zero Tolerance punishment for a single isolated incident, which derails your entire trajectory through the school system.
Right -- like "later" is one of the luckier outcomes.
Win or lose, start or end the fight, regardless of what actually happened -- there's always the extremely lopsided chance that I'm seen as the aggressor and get strongly punished; especially in the days before cell phones.
