This isn&#x27;t exactly scientific, but just go over to YouTube and read the comments whenever a woman gives a technical talk. Now imagine a role reversal where, whenever a straight male gives a talk, you can count on it receiving numerous comments from gay men saying they love a guy with brains, or how badly they want to fuck the guy (or that he isn&#x27;t attractive enough for that), or that he should go back to the garage and fix me a motorcycle. Maybe it&#x27;s only a small minority of comments, but it doesn&#x27;t take much to make the whole environment feel hostile.
