from the little I do know, the basis for tattoos historically has a more spiritual meaning and it's not just a cool and tough look like many see it as.

Campaigns like this have been offensive in the past, even when done with good intentions.

Wasn't there a bunch of uproar when BYU used do the Haka? Of course the Rugby team does their own version which seems to be received pretty well. Not sure what the difference is/was.

Personally, I think some of the designs look really cool and the passion that Rugby's version of the haka brings to the start of the match is awesome. And I love that it has a deeper meaning. So if KS and the various polynesian cultures want to share that more with the overall BYU family via football uniforms or some other manner, I'm all for it.
