Regradless of whether there is validity to a certain point of view the quickest way to lose support and credibility for that position is to have the Klan publicly endorse that view.
If you want to support affirmmative action -- join in on a Klan March. I don't know of any better way to demonstrate that racism against minorities is alive and well than to have a good ol fashioned cross burning.
These hate groups do nothing but feed the coffers of people like Al Sharpton. Time to wake up guys.
