Many Jewish gays and lesbians are seeking to establish Jewish homes. They want to celebrate the Sabbath and the holidays together, to be part of the Jewish community and even to bond the children they may chose to raise to the Jewish community. Thus they want a religious sanction for their relationship and they want their commitment to be acknowledged by Judaism so they can feel they are living a Jewish life together, with the same values of the Jewish family that our religion has always espoused - integrity, love and mutual respect. I think when they want this we should be there for them.
People often use the Bible to cite prohibitions against homosexuals.
These are all ideas that Judaism has grown beyond. The important idea here is that biblical laws were amended or sometimes suspended by Orthodox Jewish authorities as Judaism developed. Judaism developed through an evolutionary process, as does any religion, school of thought. The Orthodox who say homosexuals must be eliminated from the community wouldn't say the same thing about stoning to death a child who had cursed her mother. There was a group very uncomfortable with the subject of homosexuality being talked about and raised in such a public way.
