Michelle Bachmann tells a high school student that,
yes, a white man and black woman can too marry, only not each other. All they have to do is find someone of their own race to marry and then the law--which they must obey, because it's right!--will permit them to marry.
Oops. I got the century wrong.
Michelle wasn't talking about interracial marriage, which the law resolutely forbade for many, many years--though any white man who wanted to marry a black woman had the perfect right to marry. As long as he chose a white woman.
Michelle was talking about two men or two women marrying. Gays can most certainly marry, she tells her student questioner. All the gay man or woman has to do is find a nice partner of the opposite gender to marry.
Problem solved. Laws upheld. Impeccable logic impeccably preserved.
