"Baldness is visually enough of a stigma as it is without a big sweaty bloke on stage pointing it out"

In this quote, comedian Johnny Vegas is highlighting the negative social understanding of baldness. He recommends that being bald is currently seen as an unfavorable trait, and having somebody publicly draw attention to it just contributes to the stigma. The use of the word "visually" indicates that baldness is something that can be seen and evaluated by others. Additionally, the expression "huge sweaty chap" adds a sense of pain and humiliation to the situation. In general, Vegas is pointing out the insensitivity and potential harm in teasing someone's physical appearance, especially when it is something they can not control.
