Atheists are one of society's biggest threats. They promote no morality because they think we came from monkeys. Without God, they have no reason not to to kill, steal, molest children out of wedlock, cheat, lie, exedra.
Stalin was an atheist. Atheists aren't just mocking. They also actively encourage kids to do sex education on each other as well as homosexuality (which is even wrong in a natural sense because it doesn't produce children, even biology scientists know that homosexuality is wrong) Christians are what is holding society back from falling apart.
It doesn't matter, Once someone tells you the truth of the Gospel, you a become responsible for whether or not you accepted it. Some will accept Christ, repent of sin and enter heaven, others will continue to deny it and enter hell. It's just like the parable of the sower.
It's never a waste of time to share the gospel.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
