Q - "If you have never heard of Jesus, do you still go to hell?"
Christian A - "No. God judges you based on your understanding."
Q - "Then aren't missionaries, in essence, sending people to hell, rather than saving them?"
Seriously, though - I have a lot of trouble with people in this day and age, with the amount of information they have available to them, still believing in make believe stories that people wrote 2000 years ago. When I hear you describing how you want to "spread the gospel", I imagine what people would think of me if I stated that I wanted to spread the truth about the faeries that live in the forest and we must stop destroying their home, or they'll go back to the land of Faerie and return with an army of Fae to wipe us off the face of the earth. I fail to see any difference in logic.
We've collectively discarded the thousands of religions that have existed since the beginning of human history, yet people still cling to one - which is demonstrably misguided, if not downright evil. Much of the hate I see in the world stems from these (or very similar) superstitious beliefs. And even if, in the absence of any verifiable evidence, or basic logical examination, God does exist, then from what I've read in the bible, he's a dick and doesn't at all deserve to be worshipped.
One example of the many, many (many) logical contradictions - the first lines in the bible states: "And God said, 'Let there be light,' and there was light. 4 God saw that the light was good..."
So, this supposedly omniscient God fellow really had no idea what the hell he was doing - because he had no idea that light would be good. I guess he was just fucking around one day.
Anyways, I really wish the world would move on from these bizarre, outdated ideas that ultimately serve to make people hate each other, disregard basic science, suppress women and minorities, treat the earth as a disposable tool, value weird commandments over caring for each other, etc...
