Sorry, my further comments were intended to get the points across that:
you can't just go round changing articles because they don't reflect your point of view (there are terrible edit wars and page protections all over the place due to ethnic disputes, Serbs, Croats and Bosnians, or Armenians and Turks to give a couple of examples)
that if they are not a native speaker they should be very careful about meddling with other people's writing
And if the end result is that the person understands and stops their disruptive editing, isn't that a good thing? I am not launching a personal attack on them, let's say it's just a mild scolding.
