Do your children belong to you or do they belong to the State?
I can probably guess your answer.
Does the state think they same way that you do?
Oh. Poor public school teacher is upset that he will not be able to brainwash children unabated.
Your children are not encouraged to attend public school so that they can learn how to read or count and they certainly are not being taught a fair summation of history. They are being gathered to remove the influence of the parent and train the child in the ways of globohomo.
Homeschool your children.
