Recently, there has been an outcry against the use of racist and homophobic insults at rugby games. They do need to be banned but, so too do other remarks that are equally as insulting. References to intellect and parentage need to be banned, also references to genitalia. Insults based on sexual activity need to be rooted out, in particular those referring to masturbation and especially when combined with size.
Remarks like 'a big girl's blouse” are particularly troublesome. Big – sizism; girl - gender specific therefore sexist; blouse - infers cross-dressing, so homophobic. Colours are also a worry, black is clearly racist, ginger, when used in its Cockney rhyming slang context, is homophobic, as for yellow, say no more.
So much for the NZRU to think about. But what can the NZRU do, have fans mouths taped on arrival, magically find a mute button. Maybe the most technologically advanced solution is to have no audiences at all at matches and the game is only watched on TV in the privacy of one's home, and insults hurled can then only be heard by the screen.
