Put another way: nobody decided your name sounded too tall and refused to call you back for an interview,

Yes, but how often does a short person once they get to an interview get less likely to be hired than a tall person? This is pretty hard to test, but the difficulty in detecting a form of discrimination doesn't make it not present.

Most of your reply doesn't seem to address whether this is really a socially contestible form of power, and in so far as these are valid questions, it looks like there are signs of discrimination. For example, there are scholarships that specifically are for tall people. Source. But there is no equivalent for short people.

Maybe I should start a short persons rights movements. Best way to measure success is how many discussions about correlated biological variables we render as completely mindkilling topics. The continuous nature of the distribution is a definite problem though.
