I’m asking as a dad of two biological kids and one adopted child (though the concept of adoption differs between the West and the Arab world), ranging in age from 13 to 17. I was raised with a traditional Arab boss-subordinate dynamic between parent and child, but with my kids I went the opposite way and tried to cultivate a best-friend, mentor, and guide relationship, while still maintaining my role as an authority figure.


But by not having kids you are not a parent at all. Therefore you cannot be a great one.
Adoption exists. If you then followed most comments in this thread you could become a great parent for sure.
Yes. But you never mentioned adoption in your origional comment. If you just added that one should adopt after all that the comment starts making more sense.
But your original one does not include any of that so in that scenario a person has no biological or adopted kids and is thus not a parent.
