The bit I can't really fathom is that aside from a hastily-arranged online petition after the referendum, there's hardly been a strong opposition to the progression of the leave process. You'd expect local and national protests, picketing of MPs, media campaigns to try and get the decision overturned or reviewed.
But no, just daily bleating on The Guardian and grumbling in comments sections and online fora. I am just not compelled to believe the opposition to Brexit is actually that strong or populous.
