Readercon race-related panel brainstorming

So one of my Readercon panels is called "Guess Who's Coming to Fairyland" and is described thusly:

Many fantasy and SF novels struggle with an issue that, at first glance, looks downright old-fashioned: interracial marriage. The races are non-human, and some of their problems are unique; for example, in Cheryl Brooks's Cat Star Chronicles, the near-extinct Zetithians must breed with other species or die out. Others face very familiar concerns such as being rejected by their families or peers. Their risk-taking is often rewarded with the birth of children who display enhanced or unusual abilities--though those children have their own concerns about not fitting in. How do these themes reflect and interact with real-world tensions around race, marriage, and culture?

I've been meaning to ask you all to poke at my thoughts on this, and I just send the mod an e-mail, so now I can simply cut and paste:
