I think that is a very fair analysis

Of the situation. There is also a sense of impotence mixed into this; the solution of 'doing something', anything, that might somehow work.

'Work' as in halting the progressive march of essentially multiculturalism which of course a Brexit cannot do. Its an illusion, it means different things to different people; the Brexit campaign was almost devoid of meaning - the perfect presentation for those to 'paint' what they will upon that blank canvas, not unlike the 'Trump Wall', the 'Getting our country back' mantras.

I see this as nothing more than the panicked and confused efforts of the self disenfranchised, the newly dispossessed, or rather, those who have enjoyed essentially an inbuilt privilege, sulking because of the growing competitiveness that the EU represented. Its happening in all countries where white privilege is suffering from the simple fact of being outnumbered and consequentially dis-empowered.

In this case, the revolt started in the UK, due to the personality traits contained within the dominate culture as you accurately describe. Being 'better' than everyone else, there is less shame in being outwardly bigoted, after all, who are the Europeans to judge us.

The ironic thing in this is that the 'new Britain', alone and apart from Europe, will exhibit a home truth that will hit harder than ever following this win; absolutely nothing will change in any real sense. Not because it isn't wanted, but because it can't. The EU is a result of factors that make it necessary. We were in it because of those factors. To be outside it, we simply cannot function and maintain the prestige that out culture demands it have.

We will be outside it officially, but for all intents and purposes, the trade, immigration, legislation, corporation, movement of people and the costs incurred and everything that the Brexit campaign claimed were problems, will remain almost the same.
