Phobia - Hatred/Fear
Autophulephobia (auto-fu-lay-phobia) a hatred of ones own people, evidenced as anglophobia and cultural genocide that UK politicians continue to execute against the english people.
Cultural suicide - cultural genocide - if not, then where has everyone gone?
Defining 'Englishness' or 'Britishness' is like defining 'inteligence' - simply not possible. The closest You are likely to get to apply a test similar to that created by Alan Touring (for artificial inteligence) - and simply ask!
Because while the meaning of these words cannot be precisely or scientifically defined, English/British people can pretty reliably tell you what is and what is not 'English' and 'British'. There are many clear cut issues - Fish and Chips are an English/British thing, but Kangaroos are not. But the border, the grey area, is fractal -- the closer you look the less clear it is where the exact divide is.
One thing that has been on the rise among the English recently is a determination not to be seen as 'superior' to any other nationality/race - the plain fear of being called a 'racist'.
This, however is where things are going wrong, very wrong. The fear of being called a 'racist' has led to much English self-loathing. English people very, very keen to do down the English, however, not being suicidal the loathing is directed at *other* English people - people who are also English, but different enough not to include oneself. It is these groups of 'other english people' who are then targeted, blamed and even sacrificed by these autophulephobes. You hear it all the time 'chavs', 'pikeys', 'feral underclass' etc.
Of course the place this really makes a difference and really matters is in the hands of those with real power - in politics. The UK political class is made up almost exclusively of people who hate the English. Either because they are from one of the other 'home nations', or because they are English autophulephobes.
If you are English, rich, powerful and feeling guilty about all three how do you compensate? Well you could give up your wealth and power - but that isn't going to happen! so you are left only one option, to punish your 'Englishness', but, of course, without hurthing yourself personally. In this way the rich and powerful English come to attack, punish and destroy the English people who aren't quite 'one of them' -- and if you are a rich powerful policitian that means attacking/sacrificing the English general public.
For every English person in poor housing, in poor health, with poor education etc the rich and powerful can feel that bit less guilty about being English, rich and powerful - after all don't the English suffer and have their burden too?
Far fetched? I wish it were - but the evidence is all around us. Politicians dragging down the English - we suffer for what they, themselves, consider their sins.
