The intensity of cultural appropriation claims is proportional to the amount of plausible deniability in currency, which is most American culture at this point. We can thank the faux-prima facie legalism of American ethics for Black culture evolving to be so terribly intolerant of ambiguity. Enough Black people have had to hear the term "It's just a joke", amongst other forms of plausible deniability.I hope this helps make it clearer where this intolerance comes from. I'm not a fan of this, but transparent behavior generally takes two to tango.
