My thoughts on A.C. Grayling's letter to Parliament

A friend today drew my attention to this article by the philosopher A.C. Grayling. Below are my comments on the article:

Interesting article but I would want to question a few of Prof Grayling's premises, eg.
1) Is membership of the EU actually a term of the UK constitution (such that we have one)?
2) Should the judgement of elected representatives be given superior weight over that of ordinary citizens even when those citizens have had months to independently study the relevant facts? If so, what does this imply about the intellectual capabilities of 'ordinary people'?
3) The fact that a majority of the electorate didn't vote for Brexit is a good point but people have a right to abstain from taking part in the decision making process and to trust those with stronger views to make the decision on their behalf. Does this really invalidate the decision of the majority of those who did vote?

I did not want our country to leave the European Union but, now that the majority have voted to do so, I think that to ignore their wishes would set a dangerous and highly divisive precedent. Far better, in my opinion, to try for a post-EU deal that sees the UK retain free movement and membership of the single market, thus keeping the best aspects of EU membership while assuaging the concerns about sovereignty held by many of those who voted to leave.
