Not quite.
If we do nothing, we exit with no deal. That's the sort of Brexit many leavers imagined they supported.
If Remainers frustrate the popular decision to leave, then giving the people the opportunity to respond seems reasonable. The manifestos of both parties said they intended to leave the EU. So deselecting MPs in breach of their undertakings seems fair to me.
The EU is a wretched bureaucracy. So getting out of it, or at least releasing ourselves from much of it, seems sensible to me. But May never sold a vision of what the UK would look like on exit. People want opportunities, not to lose them.
