Loosely conflating EU membership with KKK membership?

My brother recently shared a spectator post arguing for hard brexit at some ( / any ) cost: 

This, incidentally, is one principled argument for a hard brexit, even if at some economic cost

well Rory Sutherland is a top Advertising Executive a bit of a celebrity with his very popular TED talk defending the sub-standard engineering for the UK side of the channel tunnel i.e. very crudely who cares if the train is slow through kent if we have pretty girls serving a good bottle of Pomerol?

So his concluding paragraph i.e. loosely conflating Ku Klux Klan and EU membership seems rather dangerous and a bit shameful to me

The reason I do not belong to the Ku Klux Klan is not economic. It isn’t because I resent paying the membership dues or the cost of bedsheets and firelighters. No, I haven’t joined because I do not identify with its aims and objectives. If that is reason enough not to join the Klan, it’s a perfectly sound reason to leave the EU.

Rory Sutherland is vice-chairman of Ogilvy UK.

although the headline of this peace does acknowledge that the "brexit dividend" is basically a "brexit lie" i.e. leaving the EU will make the country significantly poorer in the short to medium term.

Interestingly this has been a recurring theme in the Spectator: which although is very anti-EU, is nervous about this fundamental deception of the British people in the brexit campaign i.e. regarding the brexit dividend and 350 million/week for the NHS.
