Here in the UK, I see biracial people kind of cashing in on the concerns of white liberals to be seen to be anti racist - jobs and grants being allocated to those living with white proximity whether in their parental home or the gene pool . Most ads now feature biracial people in families with white members, happily eating, getting ready for a journey, takign out life insurance etc etc. In these sorts of ways biracial people are being courted even, celebrated. And there is the white parent or grandparent in the background.
