Do you live is a city where gangs have made inroads? Would you so be so gaily dismissive of attempts to minimze gang activity -- say by firing known gang members? Or by kicking gang members out of school? Or do you call that meanness?
The trait that makes a gang member dangerous is his (or her) embracing of violence and related tactics in day to day life. A person turned on by the same sex doesn't (necessarily) turn to violence as a top method of dispute resolution,
The inability to distinguish these things is remarkable.
