One new result in the April 2012 poll is that the percentage who strongly oppose "allowing gay and lesbian couples to marry legally" is matched by the percentage who strongly favor equal marriage rights: 22%. (Thus it means that a higher fraction of the opposition to marriage equality is strong opposition, i.e. 22 of 43 percent as compared to 22 of 47 percent.)
Among Black people, 49% oppose marriage equality compared to 39% which support it, a deficit of -10 in marriage support, the lowest gap between opposition and support for marriage equality Pew has ever found. This demonstrates that the racial disparity in views towards marriage equality is ebbing.
