Well it's not a reasonable deal is it, that's the whole point. Parliamentarians have voted against it twice already and it is highly likely that they will reject it a third time. Once again I have to reiterate that the legal position already agreed by parliament is that in the absence of a withdrawal agreement being passed, then we leave with No Deal.
It will take further legislation, to be passed by parliament and written into law, to override the default position.
I didn't write the rules. Politicians from all sides agreed this and were elected on manifesto's that said we will be leaving the EU. As for your point about leaving with a good deal. This was never part of the referendum question, in fact it is an invention made up by remoaners, losers, subverters, and the biased agenda MSM.
