The Church has excommunicated folks who were into adoring Mary.

So how can one objectively tell the difference between the adoration of Mary and the veneration of Mary? From my point of view they look exactly alike.

“So how can one objectively tell the difference between the adoration of Mary and the veneration of Mary? From my point of view they look exactly alike.”

One way to tell the difference could be to ask the people who are doing these things what they are doing. As in asking something like: “Excuse me, but are you worshipping Mary?”

How do you objectively assess the state or condition of another person's mind? Are you a mind reader?

That said, when the person "praying to" Mary or another saint specifically and explicitly, in the course of said "prayer", requests Mary or the other saint to "Pray for me" or "Pray for us" I suggest that is strong evidence that the person is NOT "adoring" Mary or the other saint.

From my point of view they look exactly alike.

I think that illustrates a flaw in your point of view.
