Mark Potok, a staff director at the Southern Poverty Law Center, which tracks hate crimes and hate groups, thinks the current noose hangings are a reaction to Jena. "What the nooses represent is a wider and deeper backlash by whites than people recognize," he says. "White people think the events in Jena were whitewashed by an evil and politically correct press.""When you hang up a noose, it's no joke to us," said [Al Sharpton] at the march. "Every noose that's hung should be prosecuted by the law. And we're going to demand that today'' According to Sharpton, the federal government has relinquished its responsibility to protect civil rights by relying on states to address hate crimes, something he characterized as a "revival of states' rights."Why are these racially motivated crimes on the rise at this point in time? Potok suggests that the recent noose incidents reflect not a fringe phenomenon, but a major social problem. "We're looking at an upsurge in racial nationalism," says Potok "What's going on is a serious backlash against globalization. You have a certain level of economic rage that provides fertile ground for these groups." He says that with more people of color immigrating to the country, "whites are angry and uneasy."
