Granted, with great sadness (and disgust), that there remains sickening bigotry and race prejudice here in the US (a recent example, via Scott, can be found here). But, granting that, fabricating racist incidents to make a point (or worse) only lends comfort to the enemy, as it both reduces the moral high ground of those who fight racism, and it discredits-by-association authentic incidents.
Indeed, one wonders whether falsely reporting such incidents — especially targeting a neighbor as the probable suspect — is not just as pernicious, and deserving of as dire consequences.
