I can sympathise with the decision, however attempting to erase history may also lead to unintended consequences.
I don't generally really like any celebration of a particular demographic simply because it is exclusive thing to do and while it may seem empowering, can also swing the other way and be dividing. It's not something that will ultimately lead to more inclusion and this seems to be becoming an increasing problem for the US now through what is becoming a seeping resentment.
