Mr. Moisi, someone probably did not warn you. But by offering your insights on the current political climate in Europe you have stepped through Lewis Carroll's Looking Glass into an alternative reality.
In this universe, the fact that you studied at the Sorbonne and Harvard.; that you are a senior adviser at the Institut Montaigne in Paris, a visiting professor at Harvard and the chairholder for Geopolitics at the College of Europe, the oldest educational institution in European affairs, and have  studied these issues all your life-- all this means nothing. In fact, it is a back mark against your, Sir.
In the universe of G&M comments, reason, logic, knowledge, fact, discussion is set aside in favour of vituperation, simplification, name calling.
Nuuance or historical knowledge is especially verbotten and ridiculed.
One-liners, trash talk and the default cry of "fake news" are the coin of this realm.
So, apologies Sir, but you must  taken have taken a wrong turn.
