Me and my girlfriend have been having a discussion for a whole day about whether or not fats are oils. We’ve googled it and the only facts we found is that fats are solids and oils are liquid, we also found that they are the same, we both agreed on that. But she also claims that oils are necessarily plant-based, which I don’t agree with.
She’s studying biology, and knows the chemistry and the proper names for things, while I have less scientific know-how, but know damn well you can use bacon fat as cooking oil. I don’t know if l’m right, moreover, I don’t know how to explain that she is wrong (if she is). Please help.

No.
Chemically speaking, “oil” just means “anything non-polar that’s mostly hydrocarbons”.
Culinarily speaking, it’s just that most vegetable fats happen to be liquid at room temperature and are called “oils” while animal fats tend to be solid at room temperature and are called “fats”, but chemically it’s all the same..
