This question arose in the context of a Jewish friend of mine who has adopted the cool crisp blonde look of a shiksa goddess even though she happens to be Jewish. But it comes up in other contexts as well, such as the Negro Raperess who dyes her hair blonde to look white, or the white boy who tries acting black. Is it a sign of racial/tribal/ethnic treason to engage in such conduct? Is it a moral crime for someone to undergo plastic surgery or for her to have herself made up to look like the members of other genetically distinct populations? Discuss amongst yourselves. As for me, with my fine goyishe good looks, that just isn't an issue.
