Earlier quoted context omitted.
I think people find it humorous because it's an unexpected instance of sexual dimorphism. Like a "Men are from Mars [not Ares]" kind of thing.
Since when is making fun of sexual dimorphism a thing? I thought we stopped doing that. Like, would it be funny if men asked women how often they think about celebrity relationships and drama? People just think about different things.
In the time since then you may have stopped thinking about sex/gender differences, but most people haven't.
I personally wouldn't find your proposal funny, but it might be more well received if you asked men vs women a question like "How often do you think about Taylor Swift's relationship with John Meyer?". That would probably get more views on your tiktoks. IMO part of the humor is that women are so surprised that men frequently think about the Roman Empire [and republic], but for the men it's a matter of course.
