That you were taught there is a stigma is clear. When and by whom? Do you recall? I  was not so taught, ergo I do not.

Stigma (sic) is a prejudice (prejudice is the apt and accurate term) directed by some against another some. None of us are required to be among those directing it.  You and you alone decide whether you are going to take part in it. That there are people taught and teaching, trained to a stigma, does not equate with there is. (Have you any doubt of that assessment see WWII, Jew stigma.)
