Gay adoption should be banned. A child deserves a mother and a father, as this is the natural state of parenting; anything else, by definition, is unnatural.
"But there are heterosexuals couple that can't reproduce, so they shouldn't have children either, as it is unnatural if they are incapable, right?"
Wrong.
No heterosexual couples that can't have kids, run around shouting how proud they are being sterile, like these degenerate gay people do, buying children and LARPing as straight people. When a couple finds out they are unable to have kids, it is seen as a tragedy. Moreoever, going back to my first point, a heterosexual couple who can't reproduce, is the only non-reproductive couple that can give an orphan the proper and natural parenting environment.
I personally don't give a shit if someone is gay, but these gay people need to keep that shit private, and stop LARPing as straight people, especially when it comes to buying children.
