I know this is an older thread but still wanna respond!
I'm white and my hubby is Filipino and we are ttc #1. Everyone, especially family, has been telling us we'll have cute kids ever since we started dating! I'd like to think that it has a little to do with us cause I don't think we are that bad looking ourselves, but I know it has to do with the fact they will be mixed race. But I don't think it's any different then if we both had red hair or blue eyes and they said "oh your kids will have the prettiest blue eyes" or "they will have awesome red hair."
I worked in a Nursery for 4 years and I think that people just find a feature on a kid to complement, for example OMG look at those dimples, she has so much hair, look at his curls, I just wanna squeeze those cheeks, look at those rolls. I think it is just a go-to cause they want to complement your kid and don't just wanna say "oh how cute."
I have heard of people getting upset when esp. stragers ask "she is so cute, what is she?" and I think that would bother me as well but we'll see if that is ever an issue since I don't get offended when people ask what race my hubby is.
I agree there is still a lot of raceism out there, I see older people staring at me and my hubby sometimes when we are out and we just hold hands and walk right by with our heads held high because we love each other and who cares what they are thinking. BUT no one is "color blind" our kids will always be asked what races they are and will most likely be told they are beautiful, I don't think that is too bad. :)
