Ideally, racism online should be countered by real, in-person conversations between the offender and a more enlightened friend, family member, teacher, neighborâ€”someone, anyone who can explain whatâ€™s wrong about hating someone for being different than you. Oftentimes, however, those people donâ€™t exist or arenâ€™t around at the right moment, and the rest of the Internet-using public is all a racistâ€™s got. But thatâ€™s not necessarily the worst outcome. Thinking prejudiced thoughts, even letting them slide out into the world, isn’t an unforgivable offense. The real tragedy would be allowing them to go undiscussed.
