Why is the clinic only open to (Korean) women?

Among the demographics that get recruited to play in the bvb tournaments, recruiting Korean women is the most difficult. Their rate of dropping out of teams leading up to a tournament is also the highest. The most common reasons for them to decline participation are:
-lack of experience
-lack of skill (and/or knowledge of the techniques)
-lack of height
-lack of confidence
-lack of familiarity with other participants
-fear of embarrassing one's self

those are among a slew of other preconceptions, many false - including the necessity to wear a bikini or speak English - which turn them away from the sport in general and the event in particular.

So this clinic is designed to break down as many of those barriers as possible and to provide for a comfortable and socially-safe environment. 

The growth of the tournament is greatly dependent on the ability to change the mindset of this demographic in particular.
