@ltdaleadergt,
We agree more than we disagree... hard to believe sometimes, but I'm convinced of it.
And I think atheists do have extreme claims. You've probably heard me say this all before.
There are two sorts of atheism. Hard atheism claims that there is no god. The hard atheist claims to know that there is no god, and that god cannot exist. Soft atheism claims that there is no reason to believe in God - there might be a God, but soft atheism points to a lack of evidence to justify disbelief.
The hard atheist has gone too far. How can anyone possible prove that there is no God? They cannot. The soft atheist, however, has a reasonable claim that I do not object to.
We can break theists down into similar categories - hard theism which claims there is a God and tries to prove that God exists, and soft theism which claims there is a God, but does not attempt to prove the existence of God to others.
There is absolutely no evidence for God that I can show you, and there is absolutely nothing you can show me that disproves the existence of God. So the hard atheist and hard theist have gone too far. Soft atheist/soft theist claims are reasonable.
