Mr. Richey's contributions, whether letters or comments on the RG's discussion site, are best understood if one realizes he's the consummate troll.....constantly "stirring the pot" seeking attention..and, remember, negative attention is better than no attention.  
Surely he realizes his letter brazenly misrepresents the political history of racism in America.  He quotes Dinesh D'Souza whose latest tretise is "his new special edition of The Glazov Gang features Dinesh D’Souza, a #1 New York Times bestselling author and author of the new book, The Big Lie: Exposing the Nazi Roots of the American Left." ...yes, indeed, we "liberals" are neo-Nazis, racist and suffer from  a "mental disorder."  Such silliness doesn't deserve an answer.  

Meanwhile,  I keep reminding myself to remember the sign by the bridge: DON'T FEEL THE TROLLS.   Gary Crum
