McLEAN, Va.—An organization that advocates so-called “ex-gay” therapy to make gays straight has settled a lawsuit with Arlington County school officials over their refusal to distribute its fliers to high-school students. As a result, the group is now considering targeting its message to even younger students in middle schools.

Parents and Friends of Ex-Gays and Gays, or PFOX, sued school system administrators and board members earlier this year in U.S. District Court in Alexandria, claiming that they improperly blocked their request to send out fliers to high school students.

School officials said all outside groups are barred from distributing fliers at high schools, basically because students don’t read them. Last month the school board formally revised its written policy, allowing flier distribution only at middle and elementary schools.

The settlement states that PFOX will have the same access given to other groups and can submit fliers for distribution to middle and elementary school students, said PFOX’s lawyer, Timothy Tracey.

PFOX, based in Fairfax County, is controversial for its support of conversion or reparative therapy, which most mental health experts say is harmful.
