Am I the only one?

That is obviously your opinion and your entitled to that.
But some people cannot have children so chosen to adopt. Children who are also being adopted havent chosen to be adopted and deserve the basic care, love and attention even if that is from their non biological parents.

I ended up having a biological child through IVF but was open to the idea of adoption if it came to it. I don't go to the effort of caring for my daughter because she happens to share some of my DNA, you grow the bond through doing all those things you've said. I wanted a child, not a child who looks like me. Making the decision to adopt is just as big and often much more of a conscious decision than having biological children. You don't adopt a child by accident. My nephews on my husband's side aren't technically blood relatives to me but that doesn't mean I love them any less than my sister's child! Obviously I don't think adoption is for everyone, it sounds like it isn't for you and that's not a bad thing at all, it's a personal preference so I selected you're the only one but not because you are, I don't think you're unusual I just don't feel the same lol

You sound like my sister's partner.
He also doesn't donate or give back to charity in any way because his time and money is his. And he doesn't see why he should take responsibility for others. Peak humanity.

Its not the kids fault their birth parents are irresponsible. I'd care for an adopted kid just the same but that's why its a long process to be a foster parent or to adopt. I'd rather care for a kid than them grow up in an abusive home or end up dieing harshly. The little things make a difference in a person and every child deserves a chance to be loved.
