1) Not terribly thrilled with being admonished in your articles every time you say something you think I might respond to, though I admit I have played a role in my status as a pariah around here.
2) I'm a Roman Catholic and strongly believe that subsidiarity cannot make a better world on its own - that solidarity is also needed. That is to say...when you talk about your church being protected from going wildly awry in total because it is cellular and autonomous, what I heard in my head is: "Then how can it be a cohesive faith that is unifying us under Christ? How cna we know that it is consistently teaching the same core values?" Catholics believe that a top-down structure is necessary but that the leity must be engaged in the faith enough to know when something has gone wrong at the top and apply the full body of Church scholarship to their discernment over whether what the Pope said today makes sense (so long as he is not speaking infallibly on a matter of faith and morals, which the Popes very...very rarely ever do). The same standard applies, to a certain extent, to international politics. I'm a conservative who believes in the necessity of free trade over protectionism. To get free trade, you have to have massive international cooperation and the nations have to have some shared say in international monetary policy.
3) Which is a longhand way of saying that I believe globalizing some values and human institutions is a good thing. I also think that space exploration should be a global effort (run by private sector companies, yes, but representing the whole world as much as possible). I am also a scientist and recognize the value of international scientific cooperation - our computer models would be useless in meteorology if the nations of the world didn't share their atmospheric and surface observation data so that we could get a proper set of initial conditions each time we make a forecast. Whatever your views on climate change, we can't do the research necessary to come to the right conclusion with international cooperation and resource sharing.
4) Where I place the limit on globalism is at the point where any concensus is possible without coersion - globalist associations must be voluntary and revokable at any time (within reason and with enough lead time to allow nations to reconfigure their business affairs) in order to be free and to work properly (and to avoid corruption such as we are constantly seeing within the United Nations).
That said, re: Brexit - I've been watching this issue for some time now. I think the EU, the way it was founded in the 1950s and extended in the 1970s made a lot of good sense. It was a loose federation of disparate states coming to common terms regarding free trade, freedom of movement, and common negotiated causes for Continental Europe. Where I think the EU has gone wrong of late, however, is in the extension of that loose Federation into a much more binding affiliation with a common charter that tries to rule over many different nationalities and many different cultures with one set of one-size-fits-all standards. When your unelected central planners in Brussels are busy regulating tea kettle power consumption for the entire continent and ordering countries that do smart economic planning to bail out countries that do incredibly stupid economic planning on a continual basis...countries that don't even share common values, no less...you're going to get a nationalist pushback and it's going to get ugly.
I think Brexit is the UK frog hopping out of the pot just before the stove gets hot enough to kill it, to use a common analogy. The EU has become increasingly aggressive in its attempts to get all of the nations of Europe to agree to one heavy-handed set of binding rules that don't make equal sense for all regions and the citizens of the UK (other than Scotland and London) have had enough of that and want to chart their own course.
TL;DR version: I am not anti-globlaist...I'm anti-multiculturalism (in the sense that I believe there should be space in this big ol' world of ours for different cultures...people should be allowed to live the way that they prefer, so long as they are not violating the human rights of other people. Societies that do not share common values soon disintegrate. It's happening here in the US, IMHO. And it's happening in the EU as well.
