Ok, but I absolutely love this bit and have come up with something similar - "Big Sister Katya" - her whole thing is that she's a 1950s/60s Soviet sympathiser, who thinks McCarthy's a complete idiot, but her personality is otherwise every bit a sheltered middle class teenage girl of the era, she's often in the kitchen with her mum or helping with some domestic task in her videos, the mum is always a voice offscreen, or partially on screen for short periods but her face isn't seen, she's seen taking care of children sometimes - her little siblings - her whole vibe is "It's the beginning of souring relations with the USSR post war, and your big sister explains why the Cold War is bullshit and neither the guys on the TV news nor Mum and Dad know what they're yapping about". It's never made clear to what extent the character she's playing genuinely believes it's the beginning of the Cold War and the peak of McCarthyism, and how much of it is "it needs to be that soon after the Great Patriotic War for some of her points about fascism and defense and good allies to land properly". Every video follows a formula of "Today we're doing [insert domestic task] with Mum/for Mum while she's out today, and discussing [insert Marxist-Leninist theory concept]".
