"I am arguing that interest/ability [science, math, engineering, and software] is not correlated with gender ... and is distributed evenly in the population."
It sounds like you are assuming, not arguing. What data do you have that substantiates such homogeneity assumptions?
"(ie. women are _not_ inherently bad at math and science)"
That "ie." is not an "ie.". Correlations or differently shaped bell curves do not translate to a simplistic summaries like "women are inherently bad at XYZ".
