Yes, to be sure, the saggy trouser "look" looks pretty stupid - more like a failure to reach the bathroom in time than a style statement - but that is hardly sufficient reason to ban it. Big earrings from the 70s look stupid too and, oftentimes, those spandex pants are a big (pun intended) sartorial mistake as well. Part of being a grown up in public spaces is putting up with the misguided style choices of others.
Surely the people who manage the transit system in Fort Worth have something more useful, and less racially tinged, to do with their time?
