They didn’t. They just avoided it and concentrated on what they thought it meant.
As you know, but I’ll just qualify this anyway

protestant groups vary greatly. I attended a ladies’ Bible study for several years, and it was never brought up. It never occurred to me there was another interpretation; you know, if you are not looking for something you don’t see it. I only remember one time that before a cradle/cultural Catholic lady arrived, the leader of the study, did say to everybody that she did not want to get into these verses because of the Catholic idea of transubstantiation. At that time, it didn’t pique my interest in learning what Catholics believe about it, but I did sort of go hhmmmmm why don’t we just talk about whatever it is? By the time, much later, I was learning about Catholicism, I was already *persona non grata *in the group so I never asked them how they would explain it.
Did the study leader understand what she was rejecting? Her husband was a graduate of a Bible college and some sort of pastor; maybe they knew and have some culpability. I don’t know. However, a lot of people are truly ignorant, and (I believe this strongly) prejudice against the Church prevents people from examining objectively what She teaches. Something has to click, reality has to switch for a second, for most to be able to get that glimmer that will lead them Home. Regarding our recent interlocutors, they have been given a lot of wonderful explanations; they have a true responsibility to read and study them with an open heart. If they don’t, they are not so innocent, IMO.
One of the incidents that started me on my way Home did occur in that Bible study, though. Before the study one day in 2005, the women were talking about the funeral of John Paul II and how Catholics worshiped him, blah, blah, blah. I couldn’t believe the nasty stuff I was hearing. I asked them if they seriously believed that Mother Teresa was in Hell?
