Actually it's far from being "very simple" because there's no universal agreement on what "idolatry" actually is. I tend to believe that most people do agree that worshiping a constructed image is "idolatry", but once we get beyond that I certainly don't see agreement.actually its very simple.
excessive admiration, or blind devotion, is doing something that directly, or indirectly, harms another because the focus is so aimed at the tree that it doesn't see the forest.
one's race could be an idolatrous thing.
one's gender, one's age, one's culture.
Again, how far does "veneration" have to go before it becomes "idolatry" is impossible to measure because there can be so many different aspects of "veneration" thus, imo, "veneration" doesn't qualify as idolatry unless the object is actually worshiped and/or expected to do certain things on its own. And as Catholics per the Catechism, we are forbidden by canon law to do that.
