Like the annual dustups over Christmas, Easter, and Hallowe’en, this fluster is the result of families’ having outsourced what should have been their own social functions to the government schools.
You are among the few who "get it".
1) Schooling can not be religiously, politically, or culturally neutral. Such a state can not exist in the mind of a sentient human. Therefore, when there are government schools, it is inevitable that lobbying blocks of citizens form in an effort to **force** their non-neutral worldview onto the hearts and minds of other people's children.
2) If education were privately delivered the problem of children who do not fit into the dominate pattern, regardless of the issue, would be handled by parents and any teachers ( if any) chosen by the parents.
3) As for this particular issue, if generations of children are subjected to socialist-entitlement and GODLESS ( or religiously lukewarm) education the community should not be surprised when LOTS of family dysfunction emerges.
