I believe that having an Asian wife is of zero value in determining whether somebody is a racist. That was what the argument was about, and you have undermined your own argument by claiming that I am a racist.
As for that claim, I honestly don't see where you're getting that from. All I said was that Webb has written a greal deal about the Scots-Irish in America as an ethnic group, and, in particular, those Scots-Irish who live in the South and in Appalachia. These are the people for whom it is politically correct to demonize as uneducated, inbred, racist rednecks. His claims that this group has suffered government oppression and deserves policy relief from that oppression, are dangerously close to the boundary which separates white supremacist rhetoric from acceptable discourse. After all, many white supremacists would say that they are only defending the rights of white people, just like black or hispanic civil rights groups work to defend the rights and interests of black or hispanic people.
As a Democrat, Webb has been able to get away with his advocacy on behalf of "rednecks." Just as Harry Reid, Joe Biden, and Bill Clinton, were given a pass for their racially insensitive remarks about Barack Obama. I think a Republican with Webb's background would have been slandered as a racist by now, to the point where his future political prospects would be nil.
Now, you may disagree with my claim, but I don't see how you can seriously argue that my claim is racist, or somehow proof of my own racism.
