Ok here's the thing. I will admit that female unicorns exist. But there is a BIG "BUT".
BUT: they simply grow out of it real fast. By early 20s they are no longier outliers. The life of a felame unicorn is simply unsustainable in this society.
There happen to be some far and few between cases of yet-unspoilt girls in their teens who think dating taller guys is shallow, or who actually have a 5'6 boyfriend, BUT IT NEVER LASTS.
It is IMPOSSIBLE for a woman to have a short bf today without all her female friends/ family members/ acquaintances, and even other men being gender traitors these days just to one-up the guy, to keep constantly reminding them that hey, your bf is short! If you dont believe that she will get literally hundreds of reminders about this, you need to eavesdrop on casual womens conversations more.
One year into a relationship with a guy that isnt at least half a foot taller than her, and she will grow to hate all short guys, because ultimately dating one degraded her self worth and image.
One more thing, these outliers are probably the moust sought-after women out there. Good luck finding one that is single.
