In many states, adoption and foster care are divorced (no pun intended) from marriage. Foster care in particular, because the system is desperate to place kids into any home they can find, and most loving, normal couples are unwilling to take in a troubled 10-year-old from a different background.
In 47 states, homosexuals can adopt children. In some states they can adopt children as a couple. Almost every state in the country allows single people of whatever sexual orientation to adopt. Florida, Utah, and Mississippi don't allow gays to adopt, but Florida at least uses homosexual households for foster care because they need to. Otherwise the kids would be on the streets.
So, does the mother giving up her child for adoption have any say in the matter, or does pro-choice only mean a choice to abort a child.
