Do better.

I have a daughter who wants to marry an Asian man, but I want her to marry someone from our race. How can I tell her without upsetting her?

You can’t. You will upset her and she will have every right to be angry with you and heartbroken over your prejudice.

Can’t you put your bigotry aside and be happy for your daughter? If you can’t, expect to see much less of your daughter in the future, if she doesn’t justifiably cut you out of her life completely.

Do better as a human being, as much for yourself as for your daughter.
