But… they can't remove citizenship retroactively. What I mean is today there are citizens and non-citizens, but there are no classes of citizens. Either you have citizenship or you do not, it doesn't matter how you acquired it.
I read this article (and others) and I am still unclear. I thought this whole idiotic crusade applied only to newly born children. It never even crossed my mind that you could revoke citizenship from your citizens. I mean, the principle of non-retroactivity dates back to the Roman Empire.
