"But if we choose to live socially, in co-operative, mutually beneficial groups, absolute freedom/selfishness must be curbed."
You attributed the above quote to me. I didn't write it. I would never write it. This sentence gives me the willies.
The problem with it is...who 'curbs' the 'absolute freedom/selfishness?" If it is not curbed by ones self, it becomes that dictatorship you decry.
the problem here is that it is not possible to have a socialist/communist government that is NOT a dictatorship. Certainly none has managed to do so yet.
Oh, and your objection to tithing, based upon historical examples of when the 'church' WAS the government, do not apply to me or my belief system, in any way. My belief system didn't exist and wasn't responsible for any of those governments, and if there is one system that is fanatic about the separation of church and state, it's mine. Shoot, even our stories regarding the Second Coming of Christ make it pretty clear that the government and the state at THAT time will be separate. We are also absolute believers in freedom of religion; it is encoded in our 'Articles of Faith" (you can call it a creed if you want).
Irrelevant, in other words. Tithing is voluntary. Taxes are not. Don't confuse the two.
