Oh I do understand this. Yet this true of any cult as well. Yet at what population of followers does a cult cease to be considered a cult and become a religion? Even Christianity was viewed as a cult at one time, same with many of the different denominations.

Now let's go with a non-Christian cult. They all instill their followers with imperatives. Things they truly believe must be done. That does not mean they are correct, and it has nothing to with science proving/disproving something which is the only thing I am addressing. I am NOT telling you that your religion is wrong, or why you should or should not speak about it. I'm only stating that science as a tool cannot prove or disprove it simply to it not being possible to get beyond the hypothesis stage in the scientific method. That's it.

Let me address what you spoke of from a Christian point of view. (Yes I was raised Christian and have many wonderful debates with Christian priests, ministers, pastors, who were friends).

Free Will.

God gave man free will supposedly. This is actually a pretty common belief outside of Christianity as well.
So why would a man be so arrogant as to tell a person to give up that free will or be damned? If you don't agree with me you are damned, you'll go to hell, etc.

Saving me

Now let's take another perspective. It isn't always the case, but in many denominations the concept comes up of "What about people that our missionaries never get to reach, to teach about Jesus? When they die are they damned?" To which I usually receive an answer that when they die they will be asked by God (or Jesus) himself.

So that leads to the question of WHY a mere man would think he should be damning people? If you as a man ask the question of another man, and they do not embrace the faith they are damned. Yet had you left them alone and they were not challenged with that question it would be God himself who asked them.
Who do you think I am more likely to believe you, or God?
So does that not kind of indicate that men are damning other men by forcing this choice upon them?

Let me spin that to a positive now. Perhaps men are living a very vile and evil life, and you believe they are likely to go to hell instead of heaven, so if they are not course corrected they may not even get asked by God.

I know quite a lot about the origin of the concept of Heaven and Hell. The concept of Heaven did exist in the Judaism as far as I can find. Yet Hell did not. In fact it was not added to Judaism until after those of this faith encountered people of the Zoroastrian faith (which was quite powerful at the time). Up until this point there was a reference to The Satan but that was simply a helper to God. The Zoroastrians had a dualistic system with a good being and an evil one in conflict, and heave and hell. It was after this that Judaism began to incorporate Heaven and Hell, and the idea of an evil being opposed to God. You see this changing of the faith to incorporate beliefs from religion continuing in history, even after Christ. December 25, is known to not be the true day that Christ would have been born. It was a very prominant pagan holiday. It was changed as such. The now popular appearance of Satan... that comes from Hades, and Pan (Greco Roman religions). In many cases they didn't fight "pagans" by forcing them to christianity, they changed Christianity to be more compelling to the pagans to switch.
