Real life Squid Game: Nazino Island, USSR 1933... 5,000 citizens rounded up and forced to "settle" a remote island with no food or building materials. Less than 1/4th survived.
Even in these conditions, the people did not think of forming groups, ambushing the guards and taking their weapons. Most likely they thought that if they went along with it, and continued to be "model citizens", the state will free them. Whoops, the answer was no.
The mantra of "do not ever let yourself be transported to a secondary crime scene" that applies to rapists and kidnappers also applies to living in totalitarian regimes. If you are part of a street roundup for instance, and you are close enough to a random guard, you KILL the fucker and get his gun immediately. If they are going to kill you, it will be right there and after you had killed a number of their own too...
Support of communism should be regarded by any functional society in the same manner as support of pedophilia and possession/download/viewing of CP. Just by supporting it, you ARE contributing to a deviant ideology which only victimizes and terrorizes.
