I don't think the haka itself is arrogant but perhaps some of the demands around it can come across that way. It is a challenge, and while I feel anthems should be respected, I don't see that the haka demands silence from the crowd (I like the haka as a tradition but part of me would love the Murrayfield crowd to sing all the way through it as a form of counter challenge - Scots Wha Hae if I were to have my preference) and the opposition players should be free to stand and face it or ignore it as they see fit. I don't even see that it should necessarily be performed between the anthems and kick off as this is perhaps what gives it its psychological advantage - implying that the All Blacks, or whichever team is performing it, are somehow worthy of greater consideration and say that their rivals. Or perhaps it being performed at that point lessens home advantage when performed during away matches - the hosts' anthem is sung second, meaning their crowd and team are hyped and it's the away team, if any, who are unnerved - putting in this pause allows the away team to hush the crowd, the home team to lose that bit of adrenalin and the performers benefit from that final boost instead. Perhaps then, it should be down to the host to specify the timing (seeing as their are already being courteous by even allowing it to be performed) - possibly at the end of the warm up perhaps, or before the anthem so still in front of a full crowd and the TV cameras.
