This is not a particularly deep thread, but it seems to me that the prevalence of 'Atheism' with a capital 'A' is growing. 'Atheism' is a common noun, not a proper noun, so in English it should not normally be capitalized (unless it is at the beginning of a sentence). However, for a time I used to hear people referring to 'Big A Atheism' implying additional values ascribed to the term beyond mere lack of belief.
For those who capitalize, is this just just an odd typing habit, or are you implying something by writing 'Atheism' instead of 'atheism'? If the latter, what is your intended meaning?
For the record, I doesn't matter to me that people use one over the other; it's just a point of curiosity as to why. Personally, I prefer it as a common noun indicating nothing more than one very simple statement of disbelief in deities.
If we were to capitalise "atheism" should we do the same to vegetarians, and feminists too?
How about someone atheize capitalism?
@Keith Murphy - If 'we' were to capitalise 'Atheism' should we do the same to Vegetarians and Feminists too?
Yay, now you are getting the idea. If catholics can use a capital C, if islam can use a capital I, I will continue to use a capital A for Atheist, to stand out, in protest, whatever. If you want to be 'real proper', then don't use a capital. Easy really.
I don't care what is 'proper', and that is just me :)
