Well, I'll take token gestures when they align with my values of caring for fellow citizens and all that jazz ... not when they align with the rise of fascism.
You sound pretty vague. Feel free to outline the purpose of that month and how it helps me care for my fellow citizens? Perhaps I would with the right reasoning.
However, your intent seems pretty weak off the bat.
For example, I'm in the UK. A black history month comes around and highlights lesser known facts around lesser known people. Doesn't bother me in the slightest and I get to enjoy some different experiences, food, and people. We also have Hindu festivals. We have Jewish festivals, etc etc etc.
Further, every other month in my country, though not explicitly called white history month, IS effectively white history month and a celebration of its culture. And I often celebrate and enjoy that element of the cultural landscape just the same.
So ... you want another month? Is that it? Interesting ... but not really.
