I mean I'm not surprised she went to defend them.
While she may be spoiled and lived from Tony's money, people seem to forget that when you take everything away, she's still his daughter. Obviously, she's aware of what he does and who's around him, but in that scene, Finn says that they acted like animals, and by extension, he thinks the same of Tony.
If anyone told me the same about my dad I'd lose my shit, and I'm pretty sure 99% of you guys would as well. And it's not without a reason!
An outsider pissing in your tent is always worse than someone in the tent doing it. This is like when Meadow told off Jackie's sister for bringing up the business in front of a civilian cousin. A lot of the things Meadow is criticized for by viewers have more to do with adolescence than mob daughter hypocrisy. We all hated our parents at that age, but if someone else talked shit about them we would be defensive.
