It seems that "More than eight-in-ten Americans (83%) now agree that "it's all right for blacks and whites to date," reflecting the most dramatic change among the racial attitudes tested in Pew polls." It's interesting that this change doesn't merely reflect cohort replacement. It's true that young people have more liberal attitudes about interracial dating, but old people's attitudes have also become more liberal over time. Interracial dating hasn't been a political issue per se for quite some time, but these changes in attitude have huge political implications as progressive politics in the United States has perennially been hampered by the country's deep racial divides.
I'm also a bit surprised by the truly overwhelming support (97 percent) among African-Americans for interracial dating, as I'd always gotten the sense that this was a pretty contentious issue in the black community.
