That's exactly my impression too. Basically, you have two types of atheists:
1. The one who rejects specific definitions and ideas of God/gods (like external personal etc), but is open minded enough to know that the word itself is vague, fluent, changes with culture, time, philosophy, etc, and won't just reject the word as such, but only rejects certain notions and definitions of what God/gods is.
2. The one who not only rejects any God concept, but rejects the use of the word "God" in any useful context. If someone says "Jonny Depp is my God" these atheist will blow a fuse and say that it's an attempt to obfuscate the standardized and objectively true atheist definition of the word "God". The word God should always be defined as the God that doesn't exist, or the definition is wrong.
I'm the atheist of the first kind, but I'm really bugged by the attitude of the second one.
