Another is the age of secularism in which we live. In a more religious America, the human being was regarded as created in God's image, a being that ideally aspires to a level of holiness. As secularism proceeds with the increasing force of an avalanche, however, man is increasingly regarded as just another animal.
One way in which higher civilizations have demonstrated the human-animal difference has been the wearing of clothing. Animals are naked in public; humans are clothed. But secularism eats away at such religious ideals. Thus religion-based concepts such as holiness and decency die out. You can see it in the widespread acceptance of public cursing as well as in public exhibitionism, among many other manifestations.
I don't know if US Airways is alone among airlines in allowing anyone to fly as long as their genitals are covered. But it seems to me that if restaurants can post dress codes and announce that they reserve the right to refuse service to anyone, an airline -- in which people, unlike in restaurants, are forced to sit two inches from strangers -- should be able to do so.
In the meantime, this is the Brave New World that mindless tolerance, diversity and lawsuits on their behalf have wrought.
