This law not only proved to America's people that it's okay to be of two different races and get married, but also helped to try to end the segregation of blacks and white in the early 1900's.
A huge reason why some people do not believe in interracial relationships is because of the mental abuse and bullying towards the couples children.
Without research, I think that most of people could say a huge positive outcome of this topic is being with the person you want to be with and not letting the people who disagree with it, come in between your relationship and beliefs.
If there is so many interracial relationships and marriages in recent generations, it must somewhat mean that the ones who don't agree either don't have very good reasoning for being against it, or don't have better things to do in life then to be judgmental towards the families and couples that are happy.
My point in this negative topic, is that there could be people in your family that do not agree with the person you are with, but at the same time, they are family and their job as a family member is to support you and be there for you.
Some Americans think interracial dating is wrong, but over half of America has been with someone of color and this is statistically shown.
