If Republicans remain silent, or worse yet, express approval of her vicious, bigoted remarks, they allow her to define the entire Republican party as vicious bigots.
A group of conservative bloggers understands this and has written an open letter to CPAC:
"...Conservatism treats humans as they are, as moral creatures possessing rational minds and capable of discerning right from wrong. There comes a time when we must speak out in the defense of the conservative movement, and make a stand for political civility. This is one of those times.
"At the Conservative Political Action Conference in 2006, Coulter referred to Iranians as “ragheads.”
She is one of the most prominent women in the conservative movement; for her to employ such reckless language reinforces the stereotype that conservatives are racists.
"At CPAC 2007 Coulter decided to turn up the volume by referring to John Edwards, a former U.S. Senator and current Presidential candidate, as a “******"...Coulter’s vicious word choice tells the world she care little about the feelings of a large group that often feels marginalized and despised. Her word choice forces conservatives to waste time defending themselves against charges of homophobia rather than advancing conservative ideas.
"CPAC sponsors, the Age of Ann has passed. We, the undersigned, request that CPAC speaking invitations no longer be extended to Ann Coulter.
Her words and attitude simply do too much damage (to conservatives)."
