there is always a lot of publicity about how the Cornish hate the English, so I don’t think I would go there on holiday. Same reason my DH won’t go to Scotland or Ireland.
The Scots and Irish don't hate the English (and a lot of the people you will encounter on a trip to Scotland have English accents anyway). And there's far more space.
we have the added problem of people from outside the area (where covid numbers have been relatively low) possibly bringing the virus with them. Can you really blame us for wishing you would all stay at home
Where I live in Hampshire the numbers are lower than in Cornwall. I know, you're going to say it's all because of those virus shedding tourists, but it isn't. The numbers haven't been high at any point where I live so there's no evidence at all that the tourists are bringing the virus with them, unless they have come from a particularly high risk area like Leicester.
