I think that, while women who want taller men are obviously a very vocal minority, this might not seem obvious to many... And to some, who are already insecure, this only makes their insecurities even worse.
My reasons for wishing I was taller are completely different, personally. I'm a trans man and, additionally, am attracted to men, so my height will never be a problem in that regard (I'm a masochist anyways), but while I'm taller than the average woman in my country (5'5"/165cm), I'm nowhere near as tall as the average man. It makes me feel like I'm less of a man and it's miserable. Worst part is I'll probably never get to transition seeing as how I'm planning to ctb this month. But hey, "one less ugly tr*nny in the world", right???
Maybe I should cover up me being trans so I don't get added to that horseshit "41%" statistic transphobic people use to feel victorious. Ugh.
