It seems to me like you've had some pretty bad experiences with Christians trying to witness to you. I don't know you personally, but it really makes me sad that you think that all of us are looking forward to you going to hell. Sometimes we do know that we can't convince you, but we have to say that we tried. And I personally would not want to see anyone go to hell if I could keep it from happening. Just because we think it won't work doesn't mean that our attempts are insincere. There's a verse in the Bible that says that one person sows, one waters, but God provides the increase. Basically that means that means that a lot of people play a part in one person coming to Christ. We know that even if you don't just automatically become a Christian, what we said had an effect and and a purpose. I hope that if you don't understand this now, you will in the future, and that you will meet a Christian that genuinely cares about you.
