There is a lot of theism vs atheism lately but as long as people remain civil it's OK, that is what people want to discuss.
A couple of things I find annoying are topics like:
Hey [theist] answer this !!!
Making it about one persons ability or inability to answer or reason is not constructive.
Chist is real, peace and praise to you, la la la
The blind assertions of God's existence and religious greetings are annoying and antagonistic. I think we can live without them.
Now here's the thing - no one is ever going to convince someone who believes in God that there is no god. The reality is that their belief is not based on ANY logical reason or evidence but purely and simply blind faith in a story they heard, usually because it was the same one their parents and grand-parents heard. If they had evidence then they wouldn't need or have faith.
Do non believers want to hear the story? No, we don't believe it and you're not going to convince anyone who thinks that God doesn't exist that he does. You have no evidence to present to people who demand evidence before belief.
So why bother with the debate? It's a little like politics - there must be swing-voters somewhere but as the late Brian Griffin once said, they are the biggest idiots on the planet if they haven't already decided.
But in the meantime, we sharpen our arguments and maybe at least learn how the other side think. Or don't ...
