The number of radical hate groups and militias has exploded in recent years in reaction to the changing makeup of America, and new census figures showing the majority of babies born in 2011 were non-white could fuel those simmering tensions, experts who track hate groups warned.
"White supremacist groups have been having a meltdown since the census bureau predicted that non-Hispanic whites would lose the majority by 2050," said Mark Potok, spokesman for the Southern Poverty Law Center, which monitors hate groups. "The demographic change in this country is the single most important driver in the growth of hate groups and extremist groups over the last few years."
The data released this week revealed a tipping point in the country's demographic shift. For the first time in the country's history, more minority children were born than white children, setting the stage for an eventual non-white majority in America's population.
The census found that 50.4 percent of births in 2011 were of Hispanic, black, Asian, and other minority children. White babies accounted for 49.5 percent of the country's newborns.
In addition, more than 49 percent of all children under 5 years old are minorities, the report said.
For white supremacist and radical right-wing groups, the data is especially troubling, and made all the more apparent by the fact that a black man was elected president, Potok said.
"This very real and very significant change is represented in the person of Barack Obama. We've of course seen the most remarkable growth in the radical right since 2008, precisely coinciding with Obama's first three years as president," he said.
According to the SPLC, the number of radical "anti-government" militia groups increased from 150 to 1,274 during the years of the Obama presidency. There have been more homegrown domestic terrorism attacks by right-wing groups than by international terrorists during his presidency as well, Potok noted.
Marilyn Mayo, co-director of the Anti-Defamation League's Center on Extremism, said white supremacist groups have increased their efforts to recruit and plot based on the changing racial makeup of America.
"I think that what we're seeing is that hate groups, particularly white supremacist groups, are talking a lot about the fact that whites will soon be a minority in this country, that their goal at all costs is to preserve the white race in civilization, which spurs them to recruit more, and have more incendiary rhetoric," Mayo said.
Mayo cited two recent plots by radical groups in Florida and Minnesota that involved stockpiling weapons for racially-motivated attacks against other Americans.
"These are just examples of people who feel like they are at a point where they have to take action because soon whites will lose power and authority and they have to protect the white race from extinction," she said.
"We're not saying that patriot militia groups are made up of klansman," he said, referring to the Ku Klux Klan. "It's more diffuse than that. It's a generalized feeling that 'this is not the country my Christian white forefathers built. We've got to take this country back.' It's not rancid straight ahead race hate, but it is very closely tied to race and the changing look of the country."
