"I think that voting leave will be worth any economic cost. And if we have a second vote, I'll still vote leave for that reason."
If you're not happy with what you see in a mirror I suggest you keep sharp objects away from your nose.

But thank you for your exposition of the attitude that brought us this unthought-out mess.
