I had someone ask me recently why, if atheism is so fulfilling, why are atheists so angry? I have been thinking about it and this is what I came up with:
Number one, atheists have to establish some kind of victimhood status so they can make it personal. They'll go back a thousand years to complain about something the Church allegedly did (and they usually make that up) to establish some level of butthurtedness. (I know, that's not a word, stay on point.) The Crusades is one of their favorites because they can make things up about that and nobody bothers to check the facts.
One of their complaints is that they claim Christianity (It's always Christianity, they never bitch about Judaism or Islam) "passes laws" that keep them from doing things they want to do, whatever that is. Well, we don't "pass laws", we have state and federal legislatures to do that. So the real problem is that we vote. The idea that people who don't believe what they believe vote is repugnant to them. So they hate freedom.
Finally, if I ever meet an atheist who has the slightest inkling of a clue about what Christianity really believes I will shake his hand and buy him a cigar. What they usually do is twist the beliefs of a doomsday cult and claim that's what the Bible teaches and what Christianity believes.
BUT, let some cult (you know who you are) speak up and they will defend them with their dying breath because they think the very fact that heretics exist must mean they have a case.
Pathetic. Hypocritical. Illogical. Non factual. Atheists.
My experience with atheists is different. Yes, some are angry, more are non-committal and matter-of-fact. As a whole they are intelligent, caring people. What I have noticed is something different than what you have picked up on.
It has been my experience that people are atheist, or become atheist, because God does not meet their expectations--neither in scripture nor in their individual life. They have their own ideas about what God would do, or would not do. God--even--or maybe especially--the one described by Christians does not live up to those ideas. Their conclusion is that there is no God, or if there is, He is useless, which is pretty much the same as no God.
If we, as Christians, are losing people to atheism, perhaps our approach to teaching about God is lacking.
