Pointing out what MPs should be working for (the best interests of the country), in contrast to what most of them actually do (give in to realpolitik) is wholly consistent.

Consistant with what?
Reality?
or your opinion?
To a rational person the two stances are most inconsistent.
(We know you offer your opinions as facts because you have admitted it)

what brexiteers are shit scared of, is that there is no actual majority among MPs for any kind of brexit at all.

Simply not true. Valiant Brexiteers are more that miffed that MPs elected on an honouring Brexit ticket are betraying their manifestos en masse. This will nor be forgotten, neither will the dwarf's devious machinations.
