If you are 'genuinely curious', than make a poll with non-troll options instead of stewing like a sore loser.
TLDR - the EU is a broken mess - I think DavidB gave a list of reasons elsewhere but my memory is: the eurozone was stupidly narrowminded, the Greek debt crisis revealed what the EU really stood for (Germany, bankers, political control), the ineptness of the refugee crisis despite my sympathies towards the refugees, the march towards a federal political union, the insane foreign policy and discriminatory political membership prioirities, the unbalanced CAP that hurts developing agricultural nations, the fishing policy, and so on. Some of these do not apply to the EU but are examples of the sinking ship the EU represents. There is also the argument that the UK has to be some sort of 'major power'. Frankly, it would better if the UK reoriented itself towards being a little England with a Japanese style foreign policy - one that engages in a peaceful and genteel foreign policy. I dislike things like the EU sanctions and being the political army of NATO.
Your 'ritual humiliation' is not leaving the EU. That already happened at Egypt and again at Iraq.
So essentially peripheral issues. If you seriously git that from the remain campaign you must be delusional.
And I would argue that losing in war is less humiliating than this. This is the equivalent of a dignified elderly person losing control of their bowels as they age. We have lost face permanently in front of the world community. And for what?
These are not peripherial issues, something that most of your country would agree with. You must be an insane tool of sorts of you think leaving the EU and giving Scotland independence is somehow more humilating and awful than colluding with the neocons in face of the UN, waging agressive war to destroy the ME, and creating ISIS.
