Nah it's worse than that.
They're telling to ignore all the real shit that's causing their issues, even to double down on them and blame not just an immutable characteristic (height), but something a lot of women (especially the really attractive ones) don't really give a shit about.
Like, I've always had a lot of women friends, and a higher than average amount have been ridiculously attractive, because absolutely more than anything else, most really attractive women want to be around people that value them for anything besides their physical attributes. The vast majority then also look at stuff other than physical attractiveness for potential partners.
All the shit about picking up women is pretending to care about the other stuff to try and get a date.
Just treat women like that in general, and women will be all over you.
Now, for disclosure I am ridiculously tall. But even my short friends did well with the same attitude
But the billionaires paying for this shit don't want men and women united, they want the average person to feel isolated and part of a small group so they can be manipulated into working against other average people instead of uniting against billionaires.
They spread sexism for the same reason they spread racism and religious bigotry.
If there's any two groups, the wealthy will try to put them against each other just so they don't unite against the wealthy. The sooner we realize that's what happening, the sooner we can actually fix shit: by taking our wealth back from Smaug.
