Here's a link to an interview with Bridget the Midget (name of her choosing), who was in the adult industry for years: http://www.ainews.com/story/5257/ She seems pretty down-to-earth about everything, including both her size & her profession of choice.

I suppose my take is that if the lady is doing it of her own accord, why the heck not? Is there a rule in the sacred stripper code that says you must be 'this tall' to don a g-string & shake your stuff? And with the shoes dancers wear, she's probably close to average height anyway by the time she's ready to work.
