@Frank Apisa,
Even if it was true that "Many spokespersons for atheism do show a marked disrespect for women (or a callousness towards them)" -- and I don't know that it's true -- it would not follow that “atheism treat women disrespectfully".
Atheism is a philosophy or set thereof, that says that the number of gods is equal to 0. It belongs to the ethereal and as far as I know gender-neutral realm of metaphysics.
For the record, I believe the number of gods can be equaled to 0 for all practical intent. Of course, for non practical use, people are allowed to dream and imagine and conjecture many magical things, and it happens to me too at times, but it serves no practical purpose other than mental comfort and the mass control allowed by organized religion.
