If you listen to the BNP talk today, this kind of behaviour would not seem amiss to people back from 1866. See this for example. Right now, the BNP is playing on fears that immigrants and non white people are taking housing and benefits which should basically go to the white race.
The national debate over reconstruction, and in particular, the Freedman's Bureau, is evident in a campaign broadside from Pennsylvania's gubernatorial campaign of 1866. This cartoon's racist imagery played upon public fears that government assistance would benefit indolent freedmen at the expense of white workers.
Needless to say, it just shows the paucity of their thinking and how racism is still working its way through the world.
