Matt Barber of the Christian conservative group Liberty Counsel on Tuesday called the NAACP's recent endorsement of equal marriage rights for gay and lesbian couples “offensive,” media watchdog RightWingWatch.org reported.

At the NAACP's quarterly board meeting in Miami last weekend, the 64-member board approved a resolution which calls gay marriage a “civil right and a matter of law.”

NAACP President Benjamin Todd Jealous went further during a press conference, warning against laws that ban gay marriage, calling them “dangerous.”

Barber criticized the NAACP's new stance, saying the group was merely providing political cover for President Obama.

Barber called the resolution “offensive,” adding: “[H]ow dare they demean and undermine and cheapen the genuine, noble civil rights movement” by supporting “deviant sexual behavior.” (The video is embedded in the right panel of this page. Visit our video library for more videos.)

Barber has previously suggested that the Defense of Marriage Act (DOMA), which bans recognition of such unions at the federal level, protects children from contracting HIV/AIDS.
