I’d thought Germany’s days as a statist tyranny were behind it, but I guess some things just never change.
Rather the opposite is true. Just imagine yourself into the situation of a orthodox muslim girl growing up in Germany. If your parents have the possibility to "homeschool" you you have NO chance to develop your own personality or to break free out of their religious dungeon. Due to our laws i.e. the Turks have to deal with kids in the meantime who already were breathing the odour of freedom. We made good experience with this practice.
There is a wide consensus among the German society that homeschooling is not wanted because we like to see the childrens right on free information assured. On one hand many parents are simply not able to teach their kids due to their own incapability on the other hand it is quite likely that religious extreme parents i.e. deprive the kids the basic information that they need to survive in our society and that they need to think in a free manner. In registered schools certain standarts are guaranteed. Parents have the right to give their kids in private schools that meet that standart and also provide i.e. a religious program of their choice. Nevertheless the individual right of the kids on information will always be more important than the collective right of the families on self-determination in Germany.
It might sound quite offensive, but Evangelical Christian parents (that are those who usually try to homeschool kids in Germany from the Christian side) practically do not play a role in our country since they are only very few people. Pratically irrelevant. It is unlikely that our laws are changed just because of this handful of Christian homeschoolers since we have to deal with much bigger groups (i.e. the 3.7% muslims in Germany) and their wish to open a parallel society. It would be idiotic to do so, since the outcome of such a policy would be for sure disastrous. Then we are not speaking about the Busekos or whatever family anymore, then we are speaking about 500.000 trapped muslim kids. As I already said - Christian parents have the possibility to found religious schools that fit into our basic standarts. Then their kids are provided with the basic information the German society considers as nessecary and the beliefs of their parents at the same time. I have no problem with that.
Therefore homeschooling is forbidden in Germany and that will not change in the future. Other countries, other attitudes.
