*Having a shorter spine causes it to take less time for messages to travel between the brain, and the rest of the body, causing faster reflexes, which is advantageous in survival in general, and in combat.
*While taller people cover more ground per step, creating an illusion of moving faster, shorter people are actually who move faster (likely due to their short spines).
*All short people have shorter spines.
*Or, alternatively, most short people have shorter spines.

*Or, alternatively, most tall people lack neoteny.

Here Are Some Contradicting Facts:
*There is more to neoteny than height. So, it is possible to be neotenous without being short, or to be short without being neotenous enough to be called neotenous by others. (However, shortness is neotenous in itself, even though there is more to neoteny than just being short.)
*The most common form of dwarfism causes one to have shorter limbs, without a shorter torso, or a shorter spine. This does not at all contribute to being more neotenous.
*In that form of dwarfism, the height they'd be if they'd have had 'proportionate' limbs can vary between short, or tall, so some of them do have shorter spines.
(It is arguable as to what is, or is not correct body part proportions to have, since it varies in our species.)
*Pro-tall heightism is not usually pro-dwarfism, contradicting itself.
*Most pro-shortists mean to be pro-neoteny.
*The stereotypes about short people in media do not reflect real tendencies. But, people in reality do try to mimic stereotypes in media. (Being short does not make a person funny, spunky, or fun. But, they are more likely to try to be so, and more likely to claim they are so.)
*People are so malnourished that size doesn't matter regarding nourishment's role in aging.
*As with neoteny, there is more to cuteness than height. So, a tall person can be cute, and a short person can lack in cuteness. (However... Shortness IS itself a cute trait.)
*Attractiveness is like cuteness. A tall person can be cute, and a short person can lack. (But, shortness is itself attractive, and those in denial are in envy.)
*While being short can contribute to being a better combatant, there are other factors to consider, such as training, and experience in combat. The shorter person can lose a fight.
*While different races have different average heights, to be pro-tall, or pro-short does not make a person racist. There are tall, and short among every race. (Though, the individual is at increased odds of being a racist due to their pro-tall, or pro-short views.)
*While different ethnicities have different average heights, to be pro-tall, or pro-short does not make a person ethnicist. There are tall, and short among every ethnicity. (Though, the individual is at increased odds of being an ethnicist due to their pro-tall, or pro-short views.)
