Is it sectarianism for one Catholic to revile or insult another Catholic, one of the taunts commonly used by Protestant fanatics? I think so. Others disagree.

A few years ago, when a newspaper columnist called me Tyga, I tried to file a complaint with the Press Complaints Commission. This did not satisfy the complaint, because the man who called me Taig was, like me, of Catholic descent, and therefore could be called Taig himself.
