Reading this made me think of a quote I heard before, "All that is necessary for the triumph of evil is that good men do nothing." If we as a community don't stand up for each other no matter the situation then who will? I work with the public and if I ever heard a coworker talking about a customer or anyone really like that I would have said something. What does it matter to them what choice of underwear someone else is wearing. Like some others have said I'd talk to the guy who is wearing the gsting or thong and let him know that he might want to keep his pants pulled up.
