Oh good, Nintendo is removing the feather. Definitely the right move as far as I can tell.
Another win for social progress. Good job, Nintendo; I love that you're willing to see that such things ARE offensive and that, while they may have been okay 30 years ago there's no reason to perpetuate it today. And no, 'adherence to tradition' is not a good enough reason to perpetuate negative stereotypes. If you think it is, then maybe you should reevaluate yourself.
Do you get upset when a Roman fighter is depicted with a laurel wreath around their head? Is that offensive?
