IRON MAN is discussing:

Where do voters stand on Brexit, after more than three years of debate and negotiation?

I wouldn't be surprised if this is an attempt to use the old psychological sales trick where you get people to answer "yes" to a number of simple questions, and then you ask them if they want to buy - they're more likely to say 'yes'.

In this case they probably want people to respond "NO!" on social media so they can somehow spin that into "Overwhelming majority are emphatic 'NO' on Brexit question".
