I was careful to refer to "Remainers in Parliament", but, yes, it's fair that a certain subset of Remainers as a whole deluded themselves for a time that Brexit could be stopped, and I was foolish enough to be part of it at the time.
Still, that's not really the charge being laid here, which is that Theresa May through her malice tried to stop Brexit from the very start. Such a charge is utter nonsense. Incompetent she may have been, but malicious she was not.
