Welcome to how it feels to be a woman, or a person of color, or gay, or any other person who his regularly discriminated against by society and a culture that elevates the white male simply for being white and male.
By ignoring the problem and not talking about it, you're perpetuating it. There is no societal problem that has been solved by not talking about it, and somehow, that is all I ever see people in the tech world suggest we do.
It's sad and narrow minded.
You say that you don't care about the sex about the person in the industry, but sexism isn't a superficial problem person to person - very little people are going to admit to being sexist or even think that they are - it's an institutional problem.
Every time that you don't say something, or you make an argument like this one, you are sending the message to people who are being discriminated against that the people who say something sexist are okay to do so.
So stop saying it's okay to not talk about. Please.
