Well that's an interesting rewrite of history. In actual fact it was May that established the red lines (no freedom of omvement, no single market, no customs union etc etc ) that pathed the way to the hard brexit we got.
And there was absolutely no moral need for Hard Brexit.
I can just about accept the "tiny majority for Brexit means Brexit has to happen" argument, but only on the condition that such a tiny majority should translate to the softest possible Brexit.
There was certainly no mandate for hard Brexit. If 13 people support something controversial for every 12 people that don't, you don't implement the controversial thing in the most strident possible way. You take into account the views of the 12, not just the 13, and implement something which keeps everyone happy.
Soft Brexit would "respect the referendum result" but would also respect the views of the 12, not just the 13. It would be a compromise. The lack of compromise is why people like myself are so annoyed, and will be until the situation changes. (And I think it will change, not to rejoin, but I do think things will soften in some way once this government is out. For example we might have closer economic ties, and slightly more freedom of movement, albeit not the full-on FoM we enjoyed in the 90s and 00s. Perhaps we will go back to the norms of the pre-EU 1973-92 period).
No, the motivation of Hard Brexit was that the Tory Party was frightened of Farage and its own right-wingers, and wanted to appeal to socially-conservative Labour seats in an attempt to win them. And the Tories have been successful in achieving those aims (to date) though I suspect this will be short lived and said seats will turn red again next year.
Finally, I think the Schengen visa-waiver scheme, and our own reciprocal scheme for EU citizens, will annoy a lot of people and turn more against Brexit. Not because of the small amount of money you have to pay, but because of the unwelcoming, US-style approach of it all. Remember it wad the Republican government of George W. Bush that started this recent trend towards visa-waiver schemes, scarcely a great role-model to follow. Even before 1973, we never had this amount of bureaucracy to travel to neighbouring countries (and neighbouring countries to us).
