It’s also a crime in some places, not (!!!) in others, or called different things in other places depending on the details.
For example, is sending an unsolicited dick pic on a dating app sexual harassment? Is getting felt up at work, with the implication ‘or else’? Is being stalked by members of the opposite gender? Or having career advancements blocked by a lack of ‘playing the game’?
I can give you concrete examples from a number of cultures that each culture will write off as ‘he/she/they were asking for it’, or ‘she/they/he deserved it’, or ‘it’s just boys/girls being girls/boys.’.
I’ve seen it up close and personal, and have lived it.
The underlying ‘attention economy’ dynamic is still the same.
Edit: meant to add - plenty of 80/20 also applies here of course (though more extreme). Top 1-2% men (esp. from earning or traditional looks perspective) deal with the same issues that top 50%-80% of women deal with, bottom 20% of women (from traditional looks perspective) deal with issues that 80-90% of men deal with, etc.
If it's okay, then it's okay for all sexes. And I'm hard-pressed to name a world culture that's equally accepting and promoting of men-sexually-harassing-women and women-sexually-harassing-men.
Can you?
It feels like you're trying to make this an argument about statistics, when it's an argument about ethics and morality.
In my book, it's reductive to sweep unsolicited sexual harassment under "attention", unwanted or otherwise.
It's not rocket science: everyone deserves to be treated in a way that makes them feel comfortable and safe.
