Better question, why should there be any particular insulation from religion? Hypothetically here in the US, a school could distribute Communist Manifestos but not have a moment of silence for prayer. What exactly is the practical difference?

One is a political system focused on running/organizing people in a practical way, the other is belief in something without proof or evidence and using it as a means to judge people and tell them what they can and cannot do. Plus in a sense note we already do this with Democracy basically, anyone can go around (even in school) and say "I love democracy, Democracy is the best". Hell when I was little schools basically made students do presentations on "How great a country Canada is" and put stuff like being a democracy as one of the reasons. But if someone went around and did the same for Communism, Marxism etc. that would be a different story.

Education already shows both political and religious bias when it shouldn't be, but both are accepted because they do it with the most popular religion/political ideology in the area.
