She has no problem showing interracial relationship because over here they aren't something one needs to make a point about. They're just something that happen. It's like saying she has no problem showing that girls can be just as clever as boys. I mean, homosexuality isn't the huge deal over her that it seems to be in the US either, but it would be more noticable in a "huh, they're gay" way than the interracial thing is.
