This is part of the leavers script 
The Mumsnet leavers can't actually debate the rationale or terms of Brexit, because, um, well, it's a bit complicated isn't it, when you try to express anything get beyond 'get control back' or what to do about Ireland, but they do feel on much more comfortable ground pretending that all remainers are elitist, middle class with a 'disdain' for the working class.
Anyone still arguing for Brexit now, MUST know that they are throwing working class people of this country under a bus (Farage's bus of lies maybe) but still - if they should loud enough about the disdain for the working class among remainers, then maybe people won't notice their culpability.
We won't forget though.
It's interesting that when I said about not having a GCSE in Economics, not watching a documentary or reading a broadsheet that your mind went - "oooh this is an attack on the working class!" Like working class people never did any of those things! Nice.
And yes, I am clearly exceptional in this way: if someone is clamoring for the EU to go by world trade rules, I am more interested if that person has 30 years professional experience of, say, international law, and yes, I do give more credibility to their arguments than my hairdressing niece. This must be shamefully undemocratic of me. 
Mind you, I know who I would prefer to give me a blow-dry.
