Should you wish to argue that the selection of the audience for question time is skewed by Pedley(the audience producer) I would agree with you.
The questionto be answered is whether question time is a political program or an audience spectacle?
I have no doubt it is the latter and the audience is chosen to provoke and court controversy for the "watching experience"
It is an equivalent of sunday night at the London Palladium with occasional serious interludes. The entire experience is manipulated for entertainment value.
Do not forget Mentorn Media owns the program and they are there to make it popular as a cash cow for the company.
The Director of Currnt affairs at Menthorn media has a background unlikely to support a rightwing extremist on the payroll.
