Evidences that we live in an amti-white culture:
#1 Anti-whiteness is embedded in the Western culture these days.
#2 In practice, you can criticize, deride and humiliate a white person for their skin color because it's socially acceptable. You can't do the same to non-whites.
#3 Liberals will try to deny it, but they have deep rooted negative biases against white people, especially against white men. They actually believe that the world would be a better place if white people are gone.
#4 White peoples' history is demonized when it's no worse (or better) than any other people.
