These studies often confuse correlation and causation. The reason why children do best in these unions is not because there is some type of magical component to traditional marriage. It is the quality of the relationship not the form of it that benefits children. The government should encourage people to be stable, committed, loving parents, regardless of their marital status or gender. The stability of a relationship is what causes children to thrive, and it is merely usually correlated to heterosexual marriage, not produced by it. Also, there are more children up for adoption than there are opposite-sex couples willing to adopt, in this sort of a world it is clearly better for children to get out of the foster care system and into a loving home. Gay parents have also faced more discrimination and exclusion than most straight parents, which makes them especially able to help children who feel unwanted or out of place in the world.
