Your employer who's afraid of a pr disaster cares. Maybe your landlord cares. Some of the more unstable mobsters might care and threaten your physical well-being. Those three points happened already, they destroyed lifes and careers.

Also I never understood the concept of "cultural appropriation", what the heck does that even mean? As long as human history goes we've been copying cultural perks from other lands, regions and tribes. To tell people this is suddenly not okay for some reason is beyond crazy.
