Actually you are using the same tactics the dummycrats use, namely no facts and just saying this is project fear.
The fact is that the UK will need to switch to American standards immediately in order to get a quick deal.
I dunno how old you are but I distinctly remember the Lefties in the U.K. making similar claims as far back as the 80s about how Britain was a poodle, Americas colony, the 51st state blah blah blah for standing firm against the Commies and not towing the supposedly sophisticated Yurp line that victory in the Cold War was impossible.....that the best Britain could do was manage its decline and other weak kneed surrender monkey crap like that.
The Leftists in Britain are Yurps at heart - forever trying to belittle Britain and act as a 5th column for the continent. The latest page out of that book is project fear II.....ie no health and safety standards, goodbye NHS, 51st State, American colony blah blah blah.
Ive seen this crap from them for DECADES.
