Being an alpha male has nothing to do with height. Short guys can be alpha male too if you don't let your height bothers you. I know of some short guys at the club who has more success in picking up chicks than their taller male counter-part because they won't allow their height to get in their way of getting the nuts. On the other hand, I have two male friends, who are both good-looking and at 6'0 and 6'1, who are at the low-end spectrum for losers. One guy always let his emotion bothers him and the other has no game or skill.
Alpha male is define by how others treat you, how you treat others and how you treat yourself. I can picture some short guys (unfortunately, usually in the mafia field) who commands respect just by the virtue of their present alone. Alpha male is not judge by material possession. That's why you often see some gorgeous women dating poor guys. The guy just needs to portray (e.g appearance and behaviour) the potential to be rich and famous. Mars Bruno (5'4?) could be an alpha male? So that's why I think short guys can be alpha... lol
And reaching 5'10 doesn't mean anything. I went clubbing and have experienced. There are many factors in making the guy popular and it's not just his height alone. Height is just one part of an aesthetic trait, like the nose, eye, skin, hair, proportion. But women judge men by the whole package, like behaviour and looks.
while i partly agree with you, you seem to have missed my point a bit. I mentioned that small guys can act alpha if they want to, but the difference is that they are much more unlikely to be recognized as alpha even when they try.
Btw getting a lot of chicks isnt enough on its own to be considered alpha, he just might have really good game with the ladies even though he might be a justin bieber type dude.
Also i mentioned that other things can compensate the short stature if short guys want to be alpha, ie if they are famous like bruno mars (although nobody i know has ever referred to Bruno Mars as alpha, most people seem to think he is a feminine dude) or supremely talented in a sport. Being highly respected in a mafia obviously compensates short stature as well, thats obvious.
However, if you are a average Joe, it is much easier to be recognized as an alpha if you are 5'10 or above (because this seems to be the height limit where you are either considered average or tall), a shorter guy will have to do a lot to compensate their height if they want to be recognized as alpha, and for some short people it might not be possible even with hard work.
