When its white guys vs minorities, minorities get a presumptive advantage because liberals see them as oppressed and whites as evil. They don't look at people and see individuals. They see groups and that's who liberals are. Its on the basis of such a worldview the farce called the DukeLax case could have proceeded as far as it did despite their being NO evidence to support the accuser's charges. People wanted and needed to believe a bunch of rich white kids could have done what happened to a young black woman. That's all there is to it.
"Show me just what Mohammed brought that was new, and there you will find things only evil and inhuman, such as his command to spread by the sword the faith he preached." - Manuel II Palelologus
