There are hard numbers on the rise of hate in America. According to the Southern Poverty Law Center, hate groups have increased 69 percent since 2000.
A "hate" group is defined as a group or movement that practices hate, hostility or violence towards another race, religion, gender or sexual orientation.
There are hate groups in almost every state in the country - 84 of them in California, 65 in Georgia. Florida, New Jersey, and Texas round out the top 5 states with hate groups.

'Swimming upstream,' white supremacist groups still strong
Hundreds of white supremacist groups are active in the United States today and are experiencing a kind of resurgence, experts say.
They are in the spotlight this week in the wake of a deadly shooting at a Sikh temple outside Milwaukee. Authorities have said they are looking into whether the gunman, who was killed, had ties to such a group.
"I know they're out there. I try not to alarm the public too much, but it's something that really needs to be taken a hold of now because more and more we see facts coming out that this is happening more often and more often, and it's not going to stop anytime soon," said David Gletty, who worked as an undercover informant on extremist groups for the FBI.
