Allow me to give you some perspective by broadening the conversation to other doctrinal issues within the LDS Church.
- We believe in abstinence before marriage and complete fidelity afterwards.
- We believe in avoiding harmful substances including (but not limited to) alcohol, tobacco, drugs, and coffee.
- We believe in keeping all of God's commandments.
Yes, this means that gays within the LDS Church are expected to live celibate as any other single member of the Church would do. Otherwise, gays may choose to marry in the traditional way as some have done. LDS Church doctrine is family - based. In order to achieve the highest level of salvation and live with families eternally, we are sealed in holy temples for time and eternity and are afterwards faithful to the covenants (promises) that we have made to each other and to God.
If you don't like this, that's fine. The LDS Church doesn't ask for approval or affirmation from any culture anywhere in the world. They only seek God's approval by teaching the gospel of Jesus Christ to the best of their ability.
