At',Steady teady... Smarter does not mean thick and I didn't say that.
You're in danger of digging yourself into a deeper hole. 'Smarter' is merely an antonym for 'thick', so 0007's interpretation of your post is spot on and I (and I fully expect all other subscribers to this thread) came to exactly the same conclusion as him.
The graph you posted shows the correlation of leave voters to people with a degree. Having a degree does not mean you're smarter than someone without one. There's no connection; it's as daft as suggesting that someone who likes modern art is smarter than someone who hates it.
My interpretation of the graph is that if you have a degree you're more likely to vote remain. The reason for this is because - as we all know - degree courses for the most part are offered by universities which are left wing remain dominated institutions. People with degrees have been indoctrinated with PC, left wing identity politics and immersed in a culture where removing the blinkers and thinking for themselves is largely frowned upon. Conversely, people without degrees are not saddled with said leftist ideology, can see past all the BS and think (very well) for themselves.
