Sorry, but what cause will white people actually march for, in regards to equality for themselves? The system in place benefits white people, and not people of color. White privilege exists, and it's for this very reason that white people cannot march for supposed racial inequality. The Klan has never been designated a terrorist group, despite historically committing terrorist acts. However, government officials and conservatives want the BLM to be labeled a terrorist organization, despite never committing terrorist acts. That's white privilege for you. Look a the Bundy clan and their standoff with the federal government, and how they were allowed to operate basically with no resistance from the Feds; now pay attention to how the Natives are being treated at Standing Rock in their protest of the Dakota Pipeline. Again, another example of white privilege at work. The day white people are treated as less than equals by the federal government in regards to other races, is the day you can march for "white equality".
