Wikipedia leaves me confused:

Atheism is, in a broad sense, the rejection of belief in the existence of deities.[1][2] In a narrower sense, atheism is specifically the position that there are no deities.[3][4][5] Most inclusively, atheism is simply the absence of belief that any deities exist.[4][5][6][7] Atheism is contrasted with theism,[8][9] which in its most general form is the belief that at least one deity exists.[9][10]


So is atheism some really stupid concept that was invented by religious people just to discriminate on non-believers? Should I even care in what category I fall?

Can't we have a term for those of us who simply don't give a fuck about religion, because it's such a ridiculous thing in the first place. Can we invent a term?

Yes, I do care enough to consider it ridiculous.
