I am Not a Fan(tm) of homeschooling and support bans of it, but forbidding them to leave is going to far.
In Plato's dialog Crito, Socrates lays out his justification for respecting the rule of law. One of his arguments in to Crito is that, while not under arrest, any Athenian remains free to leave Athens with his family and posessions.
Personally, I think Plato was sort of a hack (Plato has Crito offer only token objections) and disagree with Socrates decision to stay... BUT if the rule of law is to be respected, it seems clear to me that the freedom to opt-out must remain intact. If Germany wants to prevent these people from leaving then they should properly detain them. If they find themselves unwilling or unable to do that, then these people should be free to leave the country.
There are also German laws that place restrictions on whether and when your retail business can be open on Sundays. Or what you can say about the Nazis. Plenty of US laws are heatedly discussed here as well, often enough.
Fact is, it's not likely you can arrive at sensible conclusions about them without context or on the basis of some advocacy piece or, for that matter, Plato.
The point of the reference to Plato is that in his writings Socrates establishes a bare minimum that we should expect from a legal system if we are to respect it. Being able to leave isn't sufficient, however it is necessary.
When states start revoking passports to restrict the movement of people under their jurisdiction, they fall short of something that we should respect.
No, I got it and I don't think there is anything particularly wrong with the point itself, per se.
The basis of the point, though, is one report from an advocacy source - and here we are talking about the moral philosophy of law and statism and the Prussians and Plato. Meanwhile nobody's actually found and referenced another report of any kind. Maybe from German media. Maybe a publicly available court document. Anything.
This sort of anti-pattern makes me think that stuff like this should be mercilessly flagged off the site. If you're particularly keen on talking about it, write it up, as soberly as you can, put up some links and post that. Linking the advocacy post itself is near-guaranteed to generate almost exclusively heat at the expense of light.
