Imagine I asked you to write a page of code to do some specific thing, but told you not to run it. Then I say: Go find as many bugs in your code as you can. You come back with none, saying you've never really noticed bugs in your software. There are two possibilities:
1) Your code is naturally bug free. You are just that special.
2) You stink at finding bugs.
In this case, you're saying you don't see any bugs in your gender programming. How certain are you that #1 is true?

I'm only speaking from personal experience, of course. Take it as you will.
I think it's counterproductive for people to shift attention onto the things other "real" sexists/racists do, rather than Do Their Own Work. That's why it's productive to point out that everyone has work to be done.
I have troubles understanding that, do you have citations or examples?
Also I didn't even look at his username, so the gender really played no role.
