Charles Krauthammer has a terrific column (registration is required, so I am going to quote it from Betsy's Page)
Some Americans get angry at parents who want to ban carols because they tremble that their kids might feel "different" and "uncomfortable" should they, God forbid, hear Christian music sung at their school. I feel pity. What kind of fragile religious identity have they bequeathed their children that it should be threatened by exposure to carols?
I'm struck by the fact that you almost never find Orthodox Jews complaining about a Christmas creche in the public square. That is because their children, steeped in the richness of their own religious tradition, know who they are and are not threatened by Christians celebrating their religion in public. They are enlarged by it.
It is the more deracinated members of religious minorities, brought up largely ignorant of their own traditions, whose religious identity is so tenuous that they feel the need to be constantly on guard against displays of other religions -- and who think the solution to their predicament is to prevent the other guy from displaying his religion, rather than learning a bit about their own.
To insist that the overwhelming majority of this country stifle its religious impulses in public so that minorities can feel "comfortable" not only understandably enrages the majority but commits two sins. The first is profound ungenerosity toward a majority of fellow citizens who have shown such generosity of spirit toward minority religions. The second is the sin of incomprehension -- a failure to appreciate the uniqueness of the communal American religious experience. Unlike, for example, the famously tolerant Ottoman Empire or the generally tolerant Europe of today, the United States does not merely allow minority religions to exist at its sufferance. It celebrates and welcomes and honors them.
America transcended the idea of mere toleration in 1790 in Washington's letter to the Newport synagogue, one of the lesser known glories of the Founding: "It is now no more that toleration is spoken of, as if it was by the indulgence of one class of people, that another enjoyed the exercise of their inherent natural rights." More than two centuries later, it is time that members of religious (and anti-religious) minorities, as full citizens of this miraculous republic, transcend something too: petty defensiveness.
Merry Christmas. To all.
Krauthammer hints at the underlying psychological processes (he is a psychiatrist) of those who would try to stifle others' religious expression. It is the same self-absorbed, narcissistic envy so prevalent in our society that is behind the petty complaints and "feelings of exclusion" that appear to trump constitutional rights of free expression.
If "diversity" REALLY meant anything, then we would be joyfully celebrating ALL holiday traditions and there would be no whining about feelings being hurt by one religion's symbols or another's. Merry Christmahanakwanzakah to you!
