Oprah played a big role in my understanding of what it meant to be female and to really step into your own power. I wouldn’t even call her a role model; she was literally a reference point. You have the dictionary, you have the Bible, you have Oprah.
What is the difference between "role model" and "reference point" here? They seem similar to me.
role model: a person who someone admires and whose behaviour they try to copy (the Cambridge Dictionary)
reference point: something that is used to judge or understand something else (Merriam Webster)
