I would just say that as a leave voter I was not expecting an instant GDP increase or economic boom, it was a decision mainly based on the long term.
Let's run with that then.
So right out of the gate you're saying you thought that every prominent Leave campaigner was lying to you, so for example:
1) Easy trade deal with EU
2) Maintain the benefits of being an EU member
3) Economic boost
4) Great trade deals with major other world powers
5) No downsides/we hold all the cards
6) £350m per week for the NHS
etc etc - we all remember the bullshit.
You didn't believe any of that, i.e. you literally thought everyone in Vote Leave was lying to you, but you voted leave anyway for 'stuff' that is neither defined nor understood, that may or may not materialise years down the line, and in the meantime all the negative effects are a price for worth paying for..... 'stuff', five or ten years from now?
And the thousands of job losses, and the border in Kent, and the trashing of the UK's reputation on the world stage, and the fact that every major UK industry is at red alert, and the impending massive disruption to trade, and all the rest of it, all that's a price worth paying for 'long term' benefits?
What are those long term benefits, exactly? I ask because all the good stuff Vote Leave said would happen has vanished into thin air, and they've stopped even pretending.
