The Southern Poverty Law Center (SPLC) calls the American Family Association (AFA) a “hate group” because AFA promotes traditional Biblical views on homosexuality and marriage. SPLC does not have a standard for who they label as a “hate group.” They apply the label to whomever they want to dehumanize and attack. Surprisingly, President Obama stated the same position on homosexual marriage that AFA holds when he first ran for President, but SPLC did not call him a hater.

List of AFA's Views Regarding Homosexuality that SPLC Defines as Hateful Lies
AFA promotes the following views that SPLC calls lies:

Homosexual behavior is sinful, and a perversion of human sexuality.
Christ offers forgiveness and freedom from bondage to homosexuality or any other sin. (1 Corinthians 6:9-11).
Feeling homosexual urges does not require a person to act on them.
God ordained marriage as a union of one man and one woman in a pattern that has the potential for producing children.
No relationship between same-sex couples is really marriage, no matter what the law may say.
An intact family, with a father and a mother, is the best environment for raising a child.
Although a same-sex couple may love a child, they inevitably give the child a perverted view of sex.
Youthful partners are highly prized by homosexuals, posing a potential threat to vulnerable minors.
Homosexuals target Christians who refuse to affirm them in their sin, such as the Methodist campmeeting reception facility, the baker, the photographer, the florist and the wedding chapel operator who have been sued for not wanting to participate in homosexual wedding celebrations.
