Skin colour shouldn't matter I know it does for certain genetic diseases and for how much one can tolerate the sun, but the medical aspects aside, skin colour shouldn't matter.

People are both celebrating white heritage(these people are usually (called) racists) and black heritage. But why would we do this to begin with? Creating and emphasizing diffderences leads to polarization and racism. Why can't we celbrate history together and not single out any race?

I think the world would be a better place when the whole concept of "races" is diminished and people stop sticking with- and celebrating their own race and herirage. 

People should focus on personality, morals and values instead.
