If we are going to regulate parenting through discrimination based on; sexual orientation, ethnicity, gender, age, religious beliefs, etc. when it comes to adoption or even surrogacy, then shouldn't we in turn, force the unfit, prospective parents (those who have the ability to have their own children) to undergo surgery to keep conception from happening? We cannot withhold the opportunity to become a parent based on discriminating criteria without also governing the procreation of those who can conceive children, but are incapable of even taking care of themselves.
