Same Sex Adoption

I am linking to the recent news that the Michigan governor signed into law the right to refuse same-sex adoptions based on faith.  However, this is a much bigger issue than just this law, this is about basic human rights and how backwards we have become in our thinking.  I am straight and married, one of the best guys I have worked with in years is gay and just got married in Oklahoma, and my brother in law is gay as well and there is ZERO difference in the way we love our significant others.  In this day and age, if any company was allowed to refuse services based on race they would be lambasted and be forced to either close or change their ways and yet we are saying that exact same ideology is OK as long as it is for same-sex issues.  The only thing that should prevent an adoption should be an proven unfit home or unfit parents, there are many hetero couples who are unfit to be parents and they are still allowed to adopt and that is what is wrong with this whole scenario.
