Thanks for the thoughtful response.
It's certainly true that if we want both people to see over the wall, we'll need to give them both appropriately sized platforms for their different needs.
But I think it's worth considering that there's a difference between actions we need to do, and truths we need to realize. Giving a 5'2" person a 1' platform so that they can see as well as a 5'11" person with a 3" platform is an action that we need to do in order for them to both see over the wall. But, by contrast, recognizing the inherent problems with mislabeling things as "sacred", is not an action we need to do, but is instead a truth that we need to realize.
We need to be able to think clearly and communicate clearly in order to act effectively. And in that light, it seems like proper recognition of what's "sacred" or not is more like a math problem than like the 6-foot wall scenario.
But your article poses another question, too, namely, whether all hair stylists should be trained to cut all hair types. And that is the type of question that can be thought of in terms of the 6-foot wall scenario. Because that's not just a question of what's true, it's a question of what we should do about it. And perhaps indeed society should enforce some rules such that any person can expect a decent hair cut at any salon, even if that makes hair stylists' jobs harder.
But it doesn't seem like we need to call any hair "sacred" in order to arrive at that conclusion. We just need to recognize that having a decent hair cut is an important part of feeling confident and comfortable in life, and that, as a society, we ought to do our best to help everyone feel that way.
