It's no was near as simple as that.
First of all, we are demonstrably less likely to join TTIP due to Brexit.
Trump, Brexit and European scepticism about TTIP spell the end of transatlantic leadership on trade.

Secondly, the kitchen analogy is flawed because everyone in the UK is affected by Brexit, not just idiotic leave voters like me. Left wing politics in the UK can basically be summed up with the sentiment:
Why don't all these dumb fucks vote the way I want them to?
If the left keep on failing to grasp this very basic reality of politics they will continue to lose. Ask yourself this, if the referendum was run again would remainers really conduct the campaign in the same way?
