You seem to be the only one confused! When you said "I know that"...you evidently didn't!
Atheists are adamant in their rejection of God, or even the mention of His Name. Many atheists are even foolish enough to think they have all the knowledge to be possessed. But, to use the broadest brush, most atheists just don't like Christian people... and God is the reason!
To an atheist, it is science that holds the answers. But, to those of us with faith in a Living God, we know Who holds the keys!
I will pray that your hostility towards God will not keep you separated from Him. The results could really be hell...
Indeed.
Now, if you go over to the Religion forum you'll find many people who don't believe in the YEC interpretaion of Genesis, but adamantly profess a belief it God. A lot of them believe that evolution did happen. You don't seem willing to count them as atheists, and attack them for it, and don't really seem to consider them athiests at all. You certainly don't seem to require having someone explicitly declare their rejection of God to apply that label. Whatever meaning you're assigning to the word "atheist" doesn't seem to be based in theology. It is applied and used as a general perjorative.
