I don't really like that definition too much, it feels a little off. It feels almost like the tolerance/intolerance debate, in a way.

But I get it. I choose not to call myself an atheist, since it seems to have connotations beyond the simple definition. If asked for a label, I call myself ignostic. It has the upside of being easily mistaken for agnostic, therefore it sails under the radar when the topic of religion comes up. So I can be accurate without getting into what amounts to a political debate.
