That's debatable. Do you have any scholarly sources to back that up? Wouldn't you say that as Christians it is our duty to try to achieve as close of a "utopia" as possible through due process or 'other means'.
-- Have you even studied what Communism is according to those who originally envisioned it?
The state decides what you will do.
The state decides what you will study.
The state decides where you will live.
The state will regulate your salary.
The state will decide when/if you get medical treatment, and how much.
The state will decide if you must serve in the military.
The state will decide what goods and services are available to you.
And remember, the state is making these decisions "for the greater good of all."
Your personal opinion can be seen as divisive if you do not want what the state wants.
And if you do not agree with the state? Well, we have seen that played out before, haven't we?
And "other means" is a buzz phrase used by those who want their way by any means necessary.
The point remains: Communism is good in theory, but horrendous in actual application.
My friend, I have not only spent years studying this topic, but actually witnessed the implementations.
I lived in West Berlin during the Cold War and saw first hand what happened to those who wished to leave their "workers paradise."
You called what happened in the USSR and in China "dictatorships."
That is exactly what Communism requires to function.
If people refuse to do what the state says, the system crumbles.
Free will is the reason your utopia will not function.
The reason Christianity cannot be allowed because Christians will not obey an unjust system and will speak out.
They will not allow Communism to be their God...but that is exactly what Communism requires to function.
You are another one of those "it just hasn't been implemented correctly" proponents.
For your own good I hope you never have to find out just how misguided that thinking is.
