In the article, all the hatred is directed against tall men. The hater in the article, is a woman.
The article seems to me to be a transparent attempt to stir up envy in women. It throws in a section on short men, but ultimately suggests "recruiting" them, in the attempt to "overthrow" the tall man, who (according to the article) has gained everything he has, just because he's tall.
Study after study comes up on google (just by asking, what jobs do tall people have an advantage in) "proving" that tall men get lots more goodies, just because they're tall! So, this is supposed to be proof of injustice and hence, all short men and women have, according to the article, a "right" to resent and undermine tall men!
