I don't think abandoning or reversing Brexit is a realistic option anymore. Even 'softening' it is going to prove very, very tricky. And even if that did happen, what then? You'd still have half the country utterly seething with resentment at being cheated in this way and, as May is currently finding out, such a divided country is fùcking hard to govern. Long term, the only possible resolution is in Brexit taking place in whatever form and everyone getting used to it.
