“We haven’t attacked Ukraine either. We’re defending our territory”, “Ukraine was ours then [in USSR], too!”, “It [Ukraine] was always part of Russia”, - this Russian woman is a good illustration of how an average Russian person sees the war and Ukraine. It is a mix of propaganda, ignorance and stereotypes, with little independent thinking.
On the other hand, if you’re a Russian citizen, would you openly said bad things about Russia on camera though?
You could just say that you don’t want to talk. This person was eager to share her views.
I guess you’re right. Declining an interview is always an option.
