Atheism +

[Red Celt]

I'm a traditionalist when it comes to language. "Spokesman" is much older, 16th century, "-woman" a century or so later; "-person" can be dated back to the dark ages of 1972. Much like Englishman or chairman, the word is equally applicable to all genders. Haggling over the gender of a title merely draws attention to the title, where such attention is intended to be discouraged.

More to the point, what has any of that got to do with atheism?

Nada, nil, zilch & diddly-squat.
