A good friend and pro-life colleague of ours is a teacher who knows well the pressures brought to bear on school employees to toe the line on political correctness. This is nowhere more evident than in matters of religion, whether it involves the distortion/muzzling of one religion (Christianity) or the mindless acceptance/promotion of other religions (pantheism, Darwinism, secular humanism.)
God bless him for standing firm in the fray.
Of course, it's not just in the government schools that there's a passion to marginalize Christianity. And from this same friend came news of one of NPR's latest campaigns, "The Science of Spirituality" in which religion is reduced to merely physiological factors. God doesn't really exist. There is no divine revelation, no spirit, no authentic conscience -- it's all chemicals, baby.
Secular academics have even mapped out those areas of the brain where these notions come from. Clever blokes, huh? Uh huh; clever like a clod for as the Bible says of such arrogant rebels, "The fool has said in his heart, 'There is no God.'"
