Do you realize what is being said? To limit marriage to a certain race or ethnicity or nationality, you're limiting a LOT. People who classify themselves as say, White/Caucasian, either because they're of too many backgrounds or because they sadly don't know what they are...are they of a proposed illegal marriage? White/Caucasian and other ethnic descriptions are not one thing even though so many look at it as one.
This is retarded.
