the other vein of pro-russian tankies i’ve seen is that it’s impossible for a once communist country to backslide into fascis.

You haven't seen that because literally no one says or believes this. It's entirely your own invention, a blatant strawman.

As I always say, "If someone claims something happened on the fediverse without providing a link, they’re lying."

Didn't read anything after that because you started with such a blatant lie.
