//So enlighten me – did we get Brexit or not?//
Yes we did. The UK is no longer a member of the European Union and that's all that matters. That said, we didn't quite get the Brexit I wanted. I wanted the UK to leave without any sort of "deal" with the EU. A deal with the EU was bound to lead to problems as is becoming apparent. But what's done is done.
Of course, I'm sure you understand that Mr Farage is not saying we should not have left (or, if you do believe he is saying that, you are either mistaken or deluded). What he's saying is that the government has failed to take full advantage of it - and I quite agree with him. That's the fault of the government, firstly for agreeing to a deal which could only lead to problems but, more importantly, many in the government (and elsewhere) have seen handling the UK's departure from the EU as a damage limitation exercise rather than the opportunity to take a different path. But I'm sure you know all this anyway.
