There is no proof that an LGBT couple couldn't provide the same stable and safe home as any heterosexual couple

Parental actions and suitability matters not on sexual orientation as there are plenty of people (as evidenced by how many children are waiting for a family) who have children by conception who are completely unsuitable to be parents. Sexual orientation and gender identity has nothing to do with the child, only with the couple. As far as the child goes, a loving, safe, nurturing, development forward family is what matters.
