Nor we will he be joining in Amy Lamé's request we state one's religion as "lesbian" - though Fagburn approves.
Nor will he put "I have no religion" in that box, as the British Humanist Association argues - of which Fagburn also approves.
Fagburn shall instead just write across the envelope; "I want no part in your Lockheed Martin state snoopery, my life is none of your business - RETURN TO SENDER".
And return it to sender.
