> if it proves to be problematic in the governance of the UK, or a condition that is facilitating subversion, who is to say it couldn't be changed
Oh OK so if the EU makes an offer to UK citizens, and if some of those citizens take up the offer of their own free will, and if those citizens later become "problematic" (nice word, BTW), then the UK government may "do something about it", i.e. seek to restrict the free will and choice of their own people, presumably through legislation against membership of the EU Club as if it were, oh I don't know, more insidious than say the EDL, Britain First or Pergida, all of which are legal organisations that are also "problematic" in many people's view.
I think I see where you're coming from ...
