They do both. Russia uses as many different approaches as they can to help their mark ignore one and bond with another. It’s why they use democrats like Tulsi Gabbard to get leftist voters as well as third party candidates and right wing candidates too. Their goal is to divide people into inaction, which is just as good as ignoring or approval.
The only thing Russia doesn’t do is tell the whole truth. It’s why actually looking into sources and getting lots of varied sources defeats their approach. Russia preys on the lazy.
As we get older, our perception of time speeds up. An immortal would easily lose track of time after just two human lifetimes, causing an immortal to suffer from dementia-like symptoms where they expect one date but find themselves habitually late. And since time doesn’t mean the same thing as us to an immortal, they would eventually become disconnected from the world around them and be unable to reintegrate. They wouldn’t be able to maintain friendships, relationships, mortgages, payments, etc. They would be surrounded by people but forever alone.
