Two leaders of the campaign to win civil rights for homosexuals met on Capitol Hill yesterday with counterparts in the civil liberties and women's movements to discuss strategy against the "new right."

"We're going to start a mass educational campaign at the national and state level," said Bruce Voeller, co-director of the National Gay Task Force. "Legislation will be introduced in all the states to protect gay rights."

He and co-director Jean O'Leary said they were seeking advice from the veterans of the black and women's rights campaign on technique for winning support and forming an alliance to help one another.

"We are all facing common enemies," O'Leary said. "A new right is forming," against the Equal Rights Amendment , abortion and gay rights, she said. "As a minority group, we have a lot in common with women and blacks but there are differences, so our remedies have to be different."

The session was held in the office of Senate Majority Whip Alan Cranston (D-Calif.), because he is generally "supportive" of the homosexual right movement, Voeller said.

Besides Voeller and O'Leary, participants were leaders of the American Civil Liberties Union, the League of Women Voters, the National Organization for Women, the National Women's Political Caucus and the Women's Action League.
