In the enlightened 24th Century, the hostilities between humans and Klingons have been sorted out, the petty squabbles that dogged Captain Kirk like a malformed toupee all forgiven and forgotten. Captain Jean-Luc Picard even has a Klingon as a trusted lieutenant, whose advice he receives gratefully and always acts upon.

Except, of course, he doesn’t do anything of the sort. The prejudice of the earlier age persists. During his time on the Enterprise, poor old Worf made a billion suggestions to the slapheaded starship skipper – not to mention other members of the crew – but always got his words of wisdom shoved back into his pointy face.
