The taboos that I have mentioned are extraordinarily harsh and numerous. They stand around nearly every subject that is genuinely important to man: they hedge in free opinion and experimentation on all sides. Consider, for example, the matter of religion. It is debated freely and furiously in almost every country in the world save the United States, but here the critic is silenced. The result is that all religions are equally safeguarded against criticism, and that all of them lose vitality. We protect the status quo, and so make steady war upon revision and improvement.
