Ahem.

The referendum was advisory.

and

"MPs have voted overwhelmingly in favour of Theresa May triggering Article 50, meaning the Prime Minister is on track to begin Brexit negotiations with Brussels in March.

By 498 to 114 - a majority of 384 - MPs backed allowing the bill to progress to the next, more detailed legislative stage.

Ten Labour junior shadow ministers and three whips, who are supposed to enforce party discipline, voted against triggering Article 50 in revolt against Mr Corbyn."

To quote your own words:"what most of them(MPs) actually do (give in to realpolitik) is wholly consistent. ..... why both parties "supported brexit" after the referendum. Any party opposing the outcome of the vote would be toast."

To quote myself(again)From: Iains - PM

There is a certain inconsistency in your arguments:
You say they(mps) work for the best interests of the country ...chunder, chunder, chunder....
But!
you also say:"Well the one and only reason that the Tory referendum, then Article 50, were ratified is that the steamroller was already in full flow and that any party which voted against either would have been toast. We call it realpolitik."

seems to me you want to have your toast and eat it, and furthermore accept when it comes to survival Labour MPs would sell their aunts!

For a man that argues the sins of nitpicking you obviously hope your dual standards will not be commented on.
