OK, I will correct it to "biological" parents or is that offensive too? I asked my husband and I didn't mean anything offensive with it.
I have great admiration for people who adopt children rather than what her parents did. This is a heartwarming story and her parents are the best.
PS. I changed it to all parents instead.
"Adoptive parent" or "adopted child" aren't really offensive; they just make an unneeded (IMO) distinction between and label the children and parents, when really they are simply children and parents
"Biological" and "birth" are awkward and yeah, I guess "real" is offensive, implying that those who adopt their children or the children themselves aren't "real". Here, I guess I would refer to the parents who raised her as "her parents," and the ones who gave her up as her "birth parents."
It's all awkward, but no harm meant or done
And PS - at quick count, there are at least six people in my close family who were (past tense because I'm referring to a process that's over) adopted. They're just family, no adjectives needed
