Oh geez, another thread about short people wanting to be big to overcompensate. There are plenty of gym rats that are tall. Granted, the IFBB does have a lot of short to medium sized competitors in terms of height; however, the rare exception. Gyms contain a mixture of short to tall men all trying to get big.
Maybe they want to get huge because that's what they want. If I want to get huge, I want to get huge for ME! If some ladies don't like it, oh well. I don't go to the gym each day thinking, "oh man, I am going to pump my biceps to get the ladies tonight."
