"The logic seemed to be that if people are trained to eliminate bias in hiring, the the results will be sexist because not enough token women would be hired."

If this was implicit in your presentation, then I think I can see why you were reported to HR.

But, look, maybe you didn't deserve to be reported. Anyone can report anything to HR.

Did you mean to write explicit? The presentation wasn't actually about gender representation or affirmative action and didn't mention those things, it just had a slide or two where it pointed out that working out a fixed interview plan before doing an interview was a good way to avoid bias of various kinds, and mentioned age/gender bias as examples.

Obviously, if you're teaching people how to eliminate bias in an interview process then people who believe that absence of pro-female bias is "sexism" will consider it implicitly sexist, regardless of intent. But that's a nonsensical inversion of basic English and morality. People who report others to HR for that would be fired in any competent company (this one wasn't).
