Whilst completing an ESTA form for my upcoming trip to the United States I was asked whether I plan to commit any acts of genocide or terrorism while there: yes or no?  It’s good to know some things are still binary. I ticked "no". Homeland security can breathe a collective sigh of relief and go back to celebrating whichever identity group tops the charts this month.

It’s not a great way to screen out potential threats but it is, at least, a way of being seen to be doing something.

In the same way potential teachers in a Catholic school are asked at interview: “do you agree to uphold the Catholic ethos of the school?”, to which they reply “yes”.
