David Klinghoffer says don't be fooled, America has its established religion:
For each element of Judeo-Christian faith, secularism has its counterpart. Like Christianity and Judaism, secularism promises eternal life — well, long life, which is the central point of the most common strain of secular faith and which explains the pop-cultural focus on moral commandments having to do with physical health: Thou shalt not smoke. Thou shalt not get fat. Thou shalt fight global warming by taking the bus to work. Indeed, thou shalt vote for public subsidies for mass transit. In secularist doctrine, a fat person isn't merely unhealthy; he is a sinner in need of salvation. To address his situation, one secular gospel preaches the good news of the South Beach Diet, another that of the apostle Atkins.
It's a religion quickly gaining full ascendancy.
