I was musing a couple of days ago that people who take religious and political texts to their most radical extrapolations are usually called extremists or terrorists.
No deal is the most radical extrapolation of the referendum result. No deal Brexiteers are extremists.
And really, given they seem entirely aware at this point that the aftermath of a no deal Brexit will likely injure, kill and result in a generation’s worth of poor quality of life, it’s not far from the dictionary definition to consider no deal supporters political terrorists.
