But that's a subjective opinion isn't it?
The people who voted to leave did so because they believed they were being affected in negative ways by the EU.
They didn't like the immigration problems, the labor impacts, the fact that their representation was limited in the sense their votes only went so far, the loss of their sovereignty, the euro itself, and so on.
Sitting back and just saying "no you're wrong and ignorant now shut up and let us rule" is pretty tyrannical and is antithetical to the concepts of democracy.
Plus at the end of the day giving people the right to vote and then just saying "nah don't like the outcome" is textbook oppression.
