I disagree with that.
The conditions of leaving concern people (especially Northern Ireland, for example), as the approach taken will likely affect what terms are subsequently agreed.
if Corbyn/May negotiate like silly buggers, it'll annoy the EU and the UK will probably have a harsher Brexit effect.
If Corbyn/May negotiate like realists, I expect that Brexit will not be as harsh in its effect.
It may be closer to Sunday Times Brexit than to Farage Brexit or Daily Express Brexit, but claiming that it's not Brexit is weird.
