Among all the tricks and treats, cultural appropriation is an undeniable problem this time of year.
By “undeniable problem” she means “irresistible opportunity for moralistic preening by social leftists.” In this case, she recommends cornering those whose costumes are deemed “offensive” and delivering a stern lecture on the sin of “cultural appropriation.”
“Cultural Appropriation” is a term created by sanctimonious social leftists to attack white people who enjoy partaking of non-white, non-European culture. White entertainers that incorporate elements of African, Caribbean, or Asian influences into their art and music: jazz, for example or Kabuki-inspired costumes, are guilty of cultural appropriation. Note that “Cultural Appropriation” only goes one way; to suggest that Africans should not attempt “white European art” such as ballet or classical music would be racism. “Cultural appropriation” has been extended by the sanctimonious social left to condemn colleges that serve tacos on campus and people who dress up as ninjas or bandidos for Halloween.
In reality, “cultural appropriation” is something privileged leftists made up to lord over other people because they have no real problems and no real morality. There’s also an element of the Baby Boom Left — for whom race sensitivity rivals only hyper-environmentalism as their religion of choice — that needs to keep their pieties from dying out in the Next Generation; even as racism becomes culturally and socially irrelevant.
