"Great video: head of GOProud interviewed by retarded person on MSNBC," Coulter wrote, providing a link to this interview, in which Barron of Republican gay rights group GOProud defends the group's conservative credentials to Cenk Uygur, after invitees of the Conservative Political Action Conference boycotted the event over the inclusion of Barron's organization.
As Business Insider points out, Coulter's use of the "r-word" -- which she leveled at Uygur after he questioned Barron's decision to identify as Republican -- may put former Alaska Gov. Sarah Palin, whose youngest child, Trig, has Down Syndrome, in a tight spot.
Palin called for Rahm Emanuel to be fired earlier this year after he addressed a group of people as "f*cking retards."
"I would ask the president to show decency in this process by eliminating one member of that inner circle, Mr. Rahm Emanuel, and not allow Rahm's continued indecent tactics to cloud efforts," Palin said.
Following Rahm's comment, Rush Limbaugh also fired off an attack using the word, an action that earned him a (much less passionate) rebuke.
