Brexit

[DrPatrickBarry]

The lesson to be learned is that us plebs need to know our place, the Establishment always wins in the end.

Nope, that is not it.
In the scottish referendum the SNP produced a comprehensive document "Scotland's Future your guide to an independent Scotland" detailing Scotland's future as an independent nation. That document was analyzed to death durning the two year campaign. People on balance decided it did not work for them and voted No.

It is 670 pages

Where was the document detailing the UK future outside the EU?

People voted on the basis of propaganda and sound bites.
Many people are now realizing that what they voted for is not materializing, in fact it was never on the table, and are angry about it.
