I agree with most of what you are saying. With regard to the EU or Brexit, I think this EU thing is more complex than most of us can get our heads around. It is possible for people to be against Brexit for both good reasons and bad. If the purpose is to create alienation, separation, hatred of immigrants and to become totally isolationist and parochial - well - no - I am against that but I think Trump and Bannon are for it for those reasons. Many of the objectives of EU could still be achieved without this organizational EU. There could be a co-operative entity but without the legislative and financial powers the EU leaders exert. The entity could co-ordinate co-operation among the separate nations towards similar aims.
For consideration - Let’s expand EU into a global concept with maybe four of five different regional bodies in the world. They then could create an elite super body above all others. We are really diluting the power of local people and local institutions in favor of a so called one world government.
