For a long time I tried to resist using the term Brexiteer, because in my view there is a distinction to be made between those who thought long and hard before coming to their decision to vote leave, using their best understanding of the facts available (and are probably well aware that what is on offer now bears no relationship to what was promised) and those who demanded to leave without any serious thought whether it was good for the citizens of the country or not (and care not a jot that what is on offer now has no resemblance to what was promised, beyond empty slogans.) The former I always tried to refer to as Leavers, and the latter Brexiteers.

However, it was a losing battle, and I think those who still support Brexit seem to be Brexiteers, based on my experience.
