The second half of that post is absolute crap.The problem with Brexit is that no-one expected leave to win so no-one planned for it.
What should have happened is that after the vote a national commission of some sort should have been assembled with all the political parties and all the major industries to put together a sensible plan.
What happened instead was that the woeful Theresa Remainer May sent a single civil servant to Brussels to get shafted.
Brexit will dominate the headlines all the time that the Brexit-deniers (metropolitan elite/BBC/Whitehall civil servants) continue to whinge and whine instead of backing the country.
A single civil servant? I seem to remember a cabinet of Brexiteers going over to do the negotiations, and while the EU turned up with lawyers, we turned up with that clown David Davies armed with a pencil.
Whinge and whine instead of backing the country? You Brexiteers have had 6 years to add some Brexit value, and you've singularly failed. If people continue to "whinge and whine", that might be why.
