Kari Wagner-Peck ,the author of  A Typical Son blog, and twitter friend @atypicalson wrote a letter to find out why Chuck Klosterman , of the Ethicist used the r-word. Kari who is 'like Erma Bombeck - in that I write funny about the ordinary and not so much in that I am angry, I swear a lot, and we have a kid who has Down syndrome' wrote an eloquent, thoughtful letter to Klosterman , reached out to folks on twitter and used social media for social good. Pretty cool.  You can read the  response from Klosterman  here,It's fabulous- CK, sincerely apologizes
