I sometimes find happiness abusing myself with my left hand. I am free to do so. Government licensing and regulation isnt required. The government would have no valid reason to do so.
Sad state of affairs when you need the endorsement of government to find your happiness and feel better about yourself.
Your argument only makes sense if your left hand can take on the role of a stepparent and raise a child, and if your left hand faced discrimination on a daily basis. This isn't about "feeling better about myself". I feel great. It's about my family being valid, recognized, and given the same protections my heterosexual neighbors have. It's about my children being given the same opportunities as your children. Unless you can sit there with a straight face and prove your kids are more worthy than mine, your argument falls apart.
