You, can call that agnosticism if you like. But if I tell someone I’m agnostic vs atheist, then they have a far less accurate view of my opinions. 

By this definition, Richard Dawkins is also agnostic. It’s a view that there is no evidence of religious claims to understanding life, and a view that science explains most, not all. He’ll never tell you he can prove no god. 

Someone who says they can prove no god I agree is religious. But this isn’t a common viewpoint of people who call themselves “atheist”. 

I think atheist is a better description of my view than agnostic on a sliding scale, and I don’t enjoy being boxed into a religious because of this. I have no “faith”. Just strong opinions.
