The Southern Poverty Law Center reports that for the the first time the number of hate groups operating in the U.S. tops 1,000.
For the first time last year, SPLC included organizations like the National Organization for Marriage as anti-LGBT hate groups that promote violence.
SPLC attributes the increase to three factors:

resentment over the changing racial demographics of the country, frustration over the lagging economy, and the mainstreaming of conspiracy theories and other demonizing propaganda aimed at minorities and the government.

SPLC, based in Montgomery, Ala., has been tracking hate groups since the 1980s. The number of groups has increased during Democratic as well as Republican administrations. Every year since 2000 has seen an increase.
The most violent groups are so-called “patriot” groups that have killed eight law-enforcement officers since President Barack Obama took office.
Of the total, Texas has 59 hate groups listed, second only to California’s 68 hate groups. In Texas, the Bethesda Christian Institute in San Antonio is the only anti-gay hate group listed. Most of the Texas groups are Nazi or KKK. Dallas is home to the Confederate Hammerskins, a racist skinhead group. Fort Worth has a chapter of the Klan and a Nation of Islam group. Richardson and Irving are home to white nationalist organizations.
Only one anti-immigrant hate group is listed in Texas — the Border Guardians in Livingston, about 75 miles northeast of Houston and several hundred miles from the border.
Among the anti-gay hate groups are the Family Research Institute in Colorado Springs, the American Family Association in Tupelo, Miss., and the Traditional Values Coalition in Anaheim, Calif.
The state with the fewest hate groups is first-in-the-nation-with-civil-unions Vermont, with just two competing chapters of the Klan.
UPDATE and CORRECTION: We received a note from Focus on the Family, which I had listed with the other groups. They are not and never were one of the hate groups.
Liberty Counsel, Christian Anti-Defamation Commission, Concerned Women for America, Coral Ridge Ministries and National Organization for Marriage are groups whose anti-gay activities SPLC looked into but whose homophobia did not rise to the level of hate group.
Abiding Truth Ministries, American Family Association, Americans for Truth About Homosexuality, American Vision, Chalcedon Foundation, Dove World Outreach Center, Faithful Word Baptist Church, Family Research Council, Family Research Institute, Heterosexuals Organized for a Moral Environment, Illinois Family Institute, MassResistance and Traditional Values Coalition are listed as hate groups.
