I don't know about anyone else, but I am getting a lot of facebook posts from Brexit supporters saying we need to be supporting British farmers, repatriating businesses to the UK, we need to be self-sufficient in PPE production and the like.

Fair enough: you can make a case for that. It is about ensuring local industry is viable, even if the same goods are available cheaper from outside. It is a world of state subsidy, and import tariffs.

But it is not a world of free trade: it is a protectionist one.

Which is not entirely compatible what they were arguing before, I would say.
