Those four role models don't look like me, and I think they're all awful examples of people someone should look up to. But you need to acknowledge both sides. Stop being so stubborn and look at it objectively. We do need more diversity in role models, however by saying you want less of the current role models you are initiating a direct attack. It's tricky business either way. But perhaps it would be better to say that you wish four great role models that look like you also held such prominent mindshare.
