Legally, yes. Morally? I would say not. They are, after all, 'Honourable' members.
I'd normally agree but not in this case.
What I find immoral is that:
- the fact that it was simply advisory was apparently not on the leaflet that I've never seen;
- there was a campaign based on stoking up fear, anger and polarization;
- the referendum idea was launched at all, before having thought it through, by Cameron;
- May set off the fuse of Art 50 so soon, before any studies had been made as to the impact of various options;.
- it was originally to solve a "catfight within the Conservative party" (Verhofstadt), but which has huge and long-lasting consequences for the vast majority of UK citizens;
- it has divided not only traditional parties (which makes the situation impossible to manage), but is stoking antagonism amongst the nations of the Union and even families and friends (and I can make a wild guess as to whose agenda that might fit into);
- Corbyn is so set on his "vision" that Brexit is just a fly on the dinner table;
- many UK politicians continue to spout total rubbish (e.g. Art 24 of the GATT) when I find it incomprensible that any MP, let alone (cabinet ministers or MEPS)*, could continue to do so - pure Trumpism.
For all these reasons and I could add to them, I really do think that this shambolic situation is a mockery of democracy.
I don't expect others with a very different view to agree, but please don't shout. ;)
Typo: replaced repeating MPs by (cabinet ministers or MEPS).
