Brexit Points:
1. It is easier to reform a smaller federal government than a larger one.
2. Britain has a wonderful history and culture which will be better protected and passed on by those of the same culture in power.
3. If the UN's premise in settling international disputes falls to the principle of self-determination, then giving power to a supra-national entity over a nation would be a step backward.
4. If we see it as justice that legitimate nations(at least recognized, and had a legal foundation, I don't mean to start a flame war) were dismantled at the end of WWI because of the right of cultural self-determination, (e.g. Austria-Hungary), then again, being in the EU is a step backward.
5. Territorial/cultural disputes not successfully resolved by EU governance could involve arbitration by the UN, which again uses the right of cultural self-determination and anti-colonialism as its legal framework. This scenario seems to be an existential problem because it submits the EU to an external entity.
6. Are other countries willing to accept German dominance? (re: points 2, 3, 4, 5).
7. Bringing separate nations together with deep and conflicting histories by a distinctly secularist foundation is a gamble that Europe can be culturally unified by something other than its Christian past. Re: Pope Benedict XVI and Marcello Pera, "Without Roots."
Brexit!
