Bullshit. As the creator of the citation needed tag, I feel the urge to disabuse you of your usage of the phrase. It's self evident that if you are offensive towards women, it's less likely they will participate in IT or Computer Science.
We need more Grace Hoppers. I didn't create the {{fact}} tag all those years ago to be used for crap like this.

Of course, but that doesn't change the need for a citation of that specific claim. For instance we can observe interests in young children well before they enter our complex world with rampant sexism and bigotry, and even then we see similar patterns: girls aren't as interested in CS. Sexism is still obviously a problem in our industry, I'm not disputing that, but there's nothing wrong with requesting a source when somebody makes a claim.
Quoting the citation needed tag is just a whimsical way of stating it, there's no need for personal offense.
Your theory predicts that male geeks should also get discouraged by the abuse they receive from jocks and girls in schools and such. But that's not happening. So it looks like your theory is incomplete, or possibly wrong. We need a citation to be sure.
