Do you think it is OK to write this about white people: "White people really b on some nut shit bro"? I can understand if you write this about this girl but why does this message talk about all white race.

Post something like that about black people. If you change just one word - white => black and post it online everyone will call you racist. I'm sure almost everyone. But in our world, it is OK to write any shit about white. I don't understand this.
Writing shit about any race is wrong.
