Do you know this for sure? I'm still in Moscow 7 months in, recovering, physically & mentally, from an accident where my best friend also got killed, plus my grandparents won't have anyone to look after them if I were to leave; I've been openly opposing Putin, going on protests since before I turned 18, I've protested against the inclusion of Crimea, went on the streets when the war started etc.; I wonder, would you turn me down if I was trying to run away? After all, I've had 7 months to leave and chose not to. Or the majority of people that I was hypothetically crossing the border with did and who cares about the rest.
This logic is also used by Estonian and Finnish border control when they're turning down Ukrainians that fled from the war to Russia (because it was the only way) and stayed there longer than the border control felt was appropriate, which angers me way more than the same treatment that Russians get for obvious reasons. But it's the logic itself that is at fault. Do an interview and don't let the war supporters in, don't fecking shut down the Iron Curtain from outside.
