Earlier this year I wrote a defence of driven shooting and ended by saying I hoped my children would have a chance to participate in the sport one day. Believe it or not, I wasn’t fishing for invitations. It was intended as a piece of liberal-baiting, on the assumption that any left-wing prude who disapproves of grown men spending a day shooting game birds would find the prospect of children being inducted into this ‘barbaric’ practice even more appalling.
