Squishy - re my theories from the previous thread: You may think that my philosophical theorising is 'only theory' but you can't take the philosophy out of politics (or anything, really. We live and breathe these concepts on a daily basis). Indeed, that's why they group those subjects together on all the best courses at the best universities 
To take my theorising to its conclusion: We've got as far as - multiculturalism can't ever work because there's no way to prioritise one set of values over another (other names for this phenomenon are relativism, or any system that equalises everything without being able to foreground one thing over another). All societies, in order to function, need to prioritise one set of values over others. They need to be unitary (one law, one education system , one medical system, etc.This does not mean that you can't do your own thing or believe what you want to believe as we've seen in communist societies to date, where you even had to dress the same. This means that everyone needs to subscribe to a singularity on the fundamental substantive issues - everyone is equal before the law, in education, in medicine).
Several systems can produce a unitary society - the difference is whether the unity is produced in a top-down or bottom-up way. Top-down includes imposition of unitary values via the State (communism), charismatic individuals (fascism), groups of rich individuals (oligarchy), theocracy, etc. Bottom-up involves democratic processes. My understanding is that top-down imposition of a society's basic philosophy rarely works well for ordinary people because it goes against free will and can only be achieved via totalitarianism, but is obviously desirable to those doing the imposing . Globalisation was an attempt at an imposition of a set of values on people on a mega-scale and went against democracy. This is why we are where we are.
In my darkest moments, when I see the attempted thwarting of Brexit, the USA recount and other such things, I see the disruption of democracy and a move towards totalitarianism imposed on us via top-down processes. I find it difficult to believe that others can't see this.
