"Anyone stands in our way, they're going in the ground."

The Maryland-based branch of the hate group held the rally to protest black on white violence, President Obama, illegal immigration, LGBT rights and Jewish people.

Protest observers told Klansmen they were "disgraceful" and an "embarrassment to humans."
"We remember what you look like everybody," one protester threatened Klan supporters.
