Well, there was a little snicker above when I admitted to being white in this conversation (as if that lessened my right to speak). So expression of my ethnic connection is valid. The road goes both ways. You aren't rude and no offense taken. But here is the broader view of my position_
First, to answer your point_ The purpose of the allusion to my wife was not to the issue of prejudice as much as that we are an open thinking couple as many mixed couples are; and, as a couple representing two different races, we do not view the new president as racist. Our views are as worthy as anyone's. BUT . . . yes, I claim to be completely unprejudiced with respect to racial and ethnic differences in people. That is also our Christian belief. I do not wear it on my sleeve, but it is what I am about as a person, writer, and artist.
I write professional criticism, commentary, and fiction. I've heard it before as we all have, and I just don't care. It is not a 'badge of honor' but a point of fact. And in this discussion I only briefly mentioned my mixed marriage. One cannot marry into another culture, and embrace it, and not have a right to claim lack of (or less) prejudice. It is not logical to do so. You cannot make that life leap and not be much less prejudice, and she and I surround ourselves with friends of all ethnicities. A writer has to let their readers know where they are coming from. I'm a strong traditional conservative but quite accidentally (as if guided by God or something) my writings are about the racial situations of the 19th. and early 20th. centuries. My characters are mostly American Indian and Filipinos in the American conquered and held Philippines, and the stories involve mixed marriages and the tensions that surround them.
I do not say it often but have in published essays_ I have no prejudices based on ethnicities . . . period. I can be judgmental as to bad behavior, and each ethnic group (including whites) can have poor behavior characteristic to their own group. But it is the ones within behaving badly I judge not the group.
I have lived and worked in a nation and large city within it in which I knew only three other white adults and two small children. I was fine and comfortable with it. It just made no difference. As long as I'm treated fairly, I can walk into any room, anywhere and feel at home. It isn't about race. The feeling may have begun when as a youth in my very early twenties, I took my white date to a black only nightclub with an older clientele (30s and up) in the South just after the Civil Rights Law was passed. We were well treated by all. I knew the owner casually (had met him once) I knew no one else there.
But the roots of my comfort with all peoples may come from my parents who, living in a somewhat racist region with mildly racist friends, showed total respect for the nonwhite people they interacted with, whether alone with them or in public. We all have prejudices. Mine are not based on ethnicity. I don't give a 'whatever' who rolls their eyes; that would be their flaw not mine. They would be the one with 'attitude'. Racial 'feelings' and sensitivities need to eventually evolve.
