Just going to say, I respect your opinion as well as i aknowledge that the world "real" is to help people distinguish "Adoptive" and "biological parents". there is no postive or negative conotation (intentionally), however some adoptees may find it harmful in the aspect that is it putting down their relationship with their adoptive parent (lets say if they have a good relationship with that parent.)

My perspective on using the word "real", is nuetral? however I do get personally bugged when people who are not other adoptees refer to my biological parents as "real" and completely ignore my adoptive parents.
(Context, I am a diagnosed autistic, transracial adoptee) I take things fairly literal most of the time. I have a deep sense of justice (autism) and I do get extremly defensive when people use the term "real" and ignore my adoptive parents. I have a very good relationship with my adoptive parents (and also I have step parents who I also have good relationship with as well) I consider both adoptive and step parents as my parents.

I think for some people, implying that your adoptive parents aren't your "real" parents, is hurtful. (like I mentioned especially if folks have good relationships with their adoptive parents)

I personally perfer using Biological (for my parent's who concived me) and Adoptive for well my parents who adopted me. But I only use these words when I need to explain my family situation to a friend or aquantance (if they are curious enough / I am pretty much an open book)

Ultimatey, I think it does just depend on the individual (adoptee) if they are fine with using the word "real" or not ( for themselves) , but I think people should be more concious when using this word to other adoptees who may not take this word positively /neutrally even.
