Freeland is a Ukrainian nationalist who has no problem burning diplomatic bridges at the expense of Canada just to be able to spew vitriol. She has a history for hysterics and lying to the public: Remember her calling her family's Nazi history "Russia disinformation", despite the news having come from USA outlet Consortium News, and all the information being confirmed as true - and then Freeland even acknowledged that she had known it was true for over 10 years.
Freeland's grandfather was a pampered Nazi collaborationist, who worked to disseminate anti-Jew propaganda. Freeland's conduct through lies and Russophobic propaganda shows that she has a lot of her grandfather's character within her. Maybe when someone's career is to create and spread hostile lies about other people, the tendency to do that ends up being passed down through the family.
Also, West Ukraine isn't exactly known for being truthful, or for not being neo-Nazis. So, maybe it's partly also a Ukrainian thing.
