That you imagine you ( or atheists as a whole ) dictate language usage to the rest of us is absurd.
This is untrue and demonstrably so everytime an agnostic rejects the label atheism.
If we accept your definition then this is not true, firstly most atheists would be babies and say nothing at all, secondly you would include a group of people who consider themselves agnostic rather than atheist and finally even amongst those who we both agree are in fact atheists there is not the agreement you claim. Even a quick trip to probably the bastion of your position Secularweb and a search ( ok I'll give a link to one article there go find the rest on your own
http://www.infidels.org/library/modern/theodore_drange/definition.html ) will confirm this to anyone who doubts it. Atheists even as I define them are not in agreement, let alone atheists as you define them. Aside of all this meaning is not defined solely by those who fall into the group the label is attached to, that simply is not how language works.
What you can prove and what you believe do not necessarily line up exactly, atheism is about what you believe not what you can prove. The fact that you cannot prove your belief appears to be the driver for the sham of pretending not to hold a belief at all.
Are you seriously claiming babies do not match your definition, if you aren't your attempts to claim strawman are laughable, if you are then please demonstrate that babies do not lack belief in this area. As for the idea that babies are atheists, the idea is so far from common usage as to be perverse. I'd also note that your attempted get out that we should not speak of babies views, which ios to say beliefs, is a tad inconsistent given that you define atheism as a lack of belief, surely its either a belief or it isnt, make your mind up.
I was referring to the word atheist, I obviously failed to understand your meaning. Aside of that the word gay bears no comparison with atheism in that regard in that the word gay has indeed altered in the mainstream yet the word atheist has not.
Actually I choose to expose the dishonest attempt to slip atheism through the door dressed up as agnosticism. Nice try though. A wolf can be dressed up as a sheep but it's still a wolf.
Blah blah, 'you theists are the one whose evil conspiracy prevents people from accepting our innocent redefinition'. Laughable, if you actually believe it even more so.
