why dating a person of another race beneficial?

Highly unlikely that you'll be closely related. lol.

There are few benefits as I believe. your offsprings less likely to get genetic disorders if you are from a country where it's prone to genetic disorders, can teach each other and the children about the multiculturalism in a better way, can help to respect different races.

You'll learn about their culture and experience the prejudice they face first hand.

That builds understanding and tolerance.

almost zero change of genetic disorders in your kids

No idea, just date whomever you like and who makes you happy and treats you well regardless of race. That's all I got lol

Not sure it's as much about the race as it is the culture.

Is it? Another alternative fact I guess lol
