My comment was addressed to the HN readership in the way that most are, it's not just about OP's response. Problems with criteria for labeling someone as racist in ambiguous, subjective situations bears some importance within our dialog on racism. Saying it's out of bounds to raise issues like this, apriori, will not improve this dialog.
