Just one thing. In most of the world "Liberal" means pro-free-market mostly. Reagan, Thatcher, Schauble are all liberals.
In the USA only the world "liberal" is associated with "
Social liberal" and progressive. In most of the world, Liberal = right-wing fiscally perhaps conservative, perhaps progressive.
Now, as for the highly educated: World-wide that is not an absolute case. In USA that's not an absolute case. Yes, in USA
at the time where the conservative party is getting full of trolls, the progressive side has
somewhat more highly-educated people. But it's not like 9 out of 10 educated people are registered democrats. It's more like 3 to 2 supported Hillary over Trump. Still a big margin but if we count who the Republicans put on it
hardly makes the
progressives (Democrats are right-wing too) a club of the educated.
So, what is clear is that the Opening Post has an agenda and uses "clearly" too... liberally if I may say. It's not clear at all and the worlds "left", "conservative", "right", "liberal" etc are all used in a very specific way that doesn't reflect what they mean for most of the world.
