My impression, based solely upon personal observation is that "Drag Queens" appear to intentionally portray a "theatrically enhanced" presentation of the female gender. I am not a "Drag Queen" so that is simply personal impression, based on perception.

When I am curious about something (which is about 100% of my waking life, lol) I try to go straight to the source of my curiosity for answers, whenever possible. In my experience the further away the people get from the source...the fuzzier the explanations get. In this case I would be asking several "Drag Queens". It seems logical to expect that although their explanations would vary, they would have more credibility than those given by "outsiders" attempting to define the motivations and behaviors of "other people."

That is my strategy...
