Why one month?

What I don't understand is why do we need a Black History month? Before the hate begins, let me explain-shouldn't every month be Black History month? Hispanic History month? Asian History Month? Caucasian History month? Black history shouldn't be confined to just one month, we should learn about it every day, we should learn about ALL history every day. For far too long have we learned about history from the perspective of whites alone. Why? Because history is written by the oppressors. By the dominant. But that doesn't mean that there are not other sides to history. My point is, all history matters all the time. By confining Black history to just one month we unintentionally degrade it, despite its intentions to empower, because that means the rest of the year is only about white history. We have heard only about white history for centuries. Let's make every month Black History month, and by doing so finally embrace all cultures as equally important.
