Boycotting business because of their brexit stance
(1) As I said above, people choose to spend their money wherever they choose, and for whatever reasons they choose. There is nothing to stop Brexiters, in their greater numbers, pouring their own funds in to support pro-Brexit businesses which should therefore flourish.
(2) Surely we want all businesses to thrive going forward, unless we're advocating some sort of "enemy of the people" purge of dissident businesses? Therefore, we could take the slightly more cheerful view that perhaps all those ghastly Remoaners who are not spending money at Wetherspoons might instead be partaking at other businesses, which would therefore be enjoying extra custom - could we agree that this too would count as a success?
(3) Conversely, if people faced with a period of great uncertainty are declining to spend their money at all, we are not, I hope, proposing that they be excoriated as unpatriotic traitors against the great project?
I mean, from the way this discussion is going, it appears to me that the only "correct" (grown-up, non-vindictive, patriotic) course of action some posters would accept is to compel the populace to spend their savings and specifically at pro-Brexit businesses.
