Where same-sex households exist, they should have equal rights as opposite-sex households.  There are still many ways for gay people to become parents. Some of them are able to pay for a surrogate; some may have a natural child from a previous (heterosexual) relationship and then raise the child with a gay partner. In effect, what this law does is make it impossible for two gay people to have legal rights over a child they may already be raising together. These kids deserve the security of two legally recognized parents. If being raised by gay parents is really that harmful, why would the law allow two gay people to raise a child together as parents but refuse to legally recognize them as such?
