"Attention Passengers We Are Experiencing Turbulance Due to Sagging Pants"

I was on Yahoo poking around looking for something interesting that has happened lately to write another response too when I stumbled upon one article I found humorous, confusing, and a bit flabbergasting. The article was titled "Green Day Singer: Sagging Pants Cost Airline Seat." Reading this as a teenager who lives around too many people with their underwear hanging out, I had to read on. The article states that the lead singing of the band Green Day, Billie Jo Armstrong, boarded an Oakland-to-Burbank flight when a flight attendant approached him and asked him to pull his pants up higher. When he told her he was just trying to get to his seat, he and a companion were tossed off the flight.
So I obviously found this somewhat entertaining. I mean, who wouldn't? Some guy gets thrown off a plane for having his pants too low? Too Funny. But then I got thinking and realized, isn’t this violation of freedom of speech? Though many people detest the sagging pants look, it is a symbol of a culture and a generation. As much as I don't like to admit it, when we're forty or fifty and our kids are watching "I Love 2010" on MTV or VH1 one topic that people will definitely remember from our teenage years will be the sagging pants trend. So why does the Airline have the right to throw this guy off their planes because they don't like how he looks? I wonder if a cross dresser would get thrown off for not wearing male clothing or if a woman with multiple piercings would get thrown off for wearing an insanely large amount of body jewelry?
Though they could suggest showing your underwear is deemed inappropriate, I could easily counter that opinion with the fact that some people think showing your midriff or showing too much of your legs is inappropriate. The airline company has no right to throw Billie Joe off the flight. If this is allowed to slide without any consequences, what will happen next? Will woman have to wear floor length skirts and turtle necks on airplanes? Will men have to wear a professional suit every flight? They truth of the matter is, the only one who could tell Billie Joe he can't be in public with his pants so low is himself. Only he can decide what is appropriate for himself to wear, not a flight attendant.
