I agree it's almost pointless, but I think the point of it is to point out to TM that she'd be going against the wishes of Parliament if she allowed no-deal to occur.
That's what really gets my goat is how a few Hard Brexiteers are still parroting this line about Hard Brexit not being all that bad at all and we'll get by. It reminds me of Obama saying it's very difficult to talk to people when they don't even agree with the available facts.
I think they are a mixture of those who won't personally suffer much if at all - indeed who are almost certainly lined up to profit from it all - and those who, rightly-or-wrongly, feel they have nothing to lose because everything is crap already. Oh, and, I guess, the outright racist and those who can't cope with the fact it's not 1955 any more. And of course there's some overlap between those latter groups.
It's so hard to get a handle on it all, on who is in what category, how numerous each group is, and who is driven by which motivations.
I do feel quite weirdly mixed reactions when I hear pro-Brexit ranting because I half feel 'Oh, God, you are completely deranged!' and half feel I can empathise with where they are coming from.
The classic one is angry plebian northerner arguing with highly (privately) educated remainer (who may-or-may-not be a certain radio presenter). The remainer may have all the information and all the articulacy (gained from the public school debating society?) while the leaver is reduced to making a fool of himself spluttering entirely inchoerently about elite liberals who can prove anything with their facts and logic...and yet I still feel this weird twinge of sympathy with the angry ranter.
There are a lot of people with a lot of pent-up anger out there, and reason and facts explained in a privately-educated accent aren't going to shift them. I fear maybe it's just all too late. That brewing anger should have been addressed long before it got to this.
But I just don't know what the relative proportions are of the different pro-Brexit tribes. I don't know enough about my compatriots to get a handle on it.
I do know I blame Cameron above all for this. That Bullingdon generation were/are just not fit to run the proverbial whelk-stall. They represented a remarkable degeneration in the competence of Tory politicians since "Thatcher and the strivers".
