Actually, while I'm still thinking about the apparently heinous crime of Talking Britain Down, how about the hypocrisy of BeLeavers doing just that themselves?
It's all Talking the Talk but not Walking the Walk.
The Talk is all sunlit uplands, untold wealth for the NHS and for everybody, sovereignty, control, defiance of European tyranny over our noble peoples, being a glorious example of towering and righteous nationhood to the rest of the globe, we're going to have the best standards for human rights/food/safety, native-born English people will be awash with highly-paid employment when all the foreigners leave, etc etc.
But when it comes to the Walk: cheering on far right parties in other sovereign nations' elections because we wanted them to collapse the EU, "Trump, Erdogan, Duterte and assorted Middle East regimes aren't so bad, they're just misunderstood and we're going to be their bestest buddies", "Chlorinated chicken and hormone-filled beef are delicious and safe", "Who cares if the NHS is losing nurses", "Job losses are a price worth paying", "We may be suffering up to 100 years of economic downturn but it will be great after most of us are dead".
I mean, maybe I don't quite understand this whole BeLeaving thing, but it's not exactly sounding all positive and rosy to me.
