I have to agree. While I enjoy watching the Haka, it should not be presumed that the opposing team does or should. It is rugby, mock them, get in their heads early on. For the rest of you, there is that roundball, barf, game; where you squirm on the ground like you are mortally wounded, then when you feel you are properly rested, you can get up and run faster than you had been.
It's Rugby, donate and move on.
