Topics like this will surface repeatedly, and fizzle out after plenty of interesting ideas and conversation. And in some way, each idea has merit, and can work given the right circumstances. Some will go for a more abrupt and somewhat dispassionate approach, while others would prefer to engage people, and show them that atheists are good people, and that there is no reason to think that people cannot be good without a god.
In the end, its going to take the full combination of approaches, I think. We need it all. We need sympathy, and we need spite. We need to marginalize the believers, and we need to embrace them. After all, they are only human, and humans do not respond identically in such circumstances. More importantly, in my opinion, we need to find ways to get the youngest people to think for themselves. We need to find ways to nurture independent thought, and critical thinking at very young ages. And not about gods or religions, or even science - but about everyday reality!
I think about my nine year old son, who has been teased in some ways from Christian friends. He has never had to defend himself, but they ask him what Church he goes to, or some other mundane religious based thing. He changes the subject, because he knows it will hurt feelings, and he also does not want to feel alienated by his friends. It's his life, but I encourage him to stretch out a little more each time, and take a small risk. I'm waiting to see when and how he might choose to do this. Will he offend a friend, or will he simply say that he is not ready to decide what he believes, and let his friends babble on in their brainwashed state (as if a child has any way to defend their god beliefs).
Tolerance is an interesting, and often effective message with younger people, but it has to go both ways, and we have to find ways to teach our youngest that if tolerance is not afforded to everyone, it is not tolerance. That seems to be the biggest problem I see with religiously brainwashed kids these days - and they get them very young. These kids have no way of defending their "beliefs", because they did not arrive at those beliefs on their own (typically)...
I could go on...but I will take a rest and see where the conversation goes.
Love this topic.
