I think short guys should be called boys not men regardless of age
Is there a reason that you say that?
yes. I hate shorter guys for being intimidating.
Have you considered that you being so tall is intimidating to them? You cannot be judging someone just based on their size.  How would you feel if they were doing that to you?
They should just respect the alpha male size hierarchy.
I'm not sure what you mean by that, but there's no such thing as a size hierarchy. It seems to me that you should stop worrying about people's sizes so much in general!
