It is true what I stated. But no way does it stop the prejudices against short people. Society is shallow, arrogant, and not very nice. That is the reality..But simply to say someone is inferior just on the premise ofheight is completely inaccurate.
What a bad society, huh? Of course, we should fight it, we should protest against prejudices, huh, ok. Gotcha.
But why all those struggles for the sake of great justice if you can simply. Change. Yourself. Surgically?
I will follow your points, to demonstrate what greater height can do.
2) You might be able to better represent your talent, be more appealing to an audience, and not be ashamed of yourself.
3) It might have influence on your character. There is no need to reach extremes, - generally, a short person suffering from BDD will be happier overall, and this can significantly influence their character.
4), 6) You're wrong. Let's play Darwinian, - greater height up till certain extent associates with better health and is overall more appealing. It's also speculative at best that short people live longer. Can't comment on sicknesses, since it's just too broad and vague topic to discuss.
5) Height has SOMEthing to do with athletic abilities. Simone Biles can't be a swimmer like Phelps even if she wishes very, very hard. Also, Phelps couldn't be, you know, Phelps, had he not his stature and proportions. (Vice versa, of course, Phelps can never be someone like Biles).
Different sports require different heights, and that's true. However, what can you say to a boy like me who couldn't compete with other boys in swimming after puberty anymore, I don't know. Advice to change sports, huh?)
7) Beauty is subjective, but not that subjective. Again, we play Darwinian here. Greater height up till certain extent associates with better health and is overall more appealing. Yes, you said that there are handsome short people and there are ugly tall people. But be they taller, short ones would be even prettier, and be they shorter, tall ones would be uglier. Sad, but true.
I missed the first 1) obviously, since mechanical change of height can't increase your intelligence, which is obvious. However, again, taller people are more likely to be smarter than their short buddies, since, again, it's all about genes and environment (the latter we consider to be equivalent for everyone, for the sake of argument). Sorry.
In closing, greater height provides you more opportunities. But of course, we should fight with prejudices instead.
