I know hardcore brexiteers would have a heartattack... but I'd have a lot of respect for boris+co or any brexiteer who came out and just said "Look, normally I support brexit, because of the potential longterm plan, but its always going to come at a short-term cost, and given the current crisis we can't take a short term hit of any kind, so lets shelve it for a while until things are better again, and then restart negotiations/talks then"
