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).
