As a previous long-time resident of Virginia from 1995 to 2010, I personally knew several friends who were both voluntarily AND involuntarily subjected to this practice, while living there.  My friends ranged in age from upper teens to lower 40's.  Regardless of their age, the result was always the same--failure and long-term psychological damage. 

This therapy attempts to change something innate and biological, and there is neither scientific basis that validates the effectiveness of such therapy, nor is there any valid evidence that refutes the damage it causes to innocent people.  This type of treatment is a cover for hateful or bigoted attitudes and inflicts real harm on individuals who experience it--often young people who are forced into such programs. 

There is a reason major medical and psychological associations recommend banning it, because it overtly harms people and drives them into unhealthy psychological anguish and even can resultd in attempted suicides (in the case of my friends).

Do Virginia a huge favor, and join other states in banning this barbaric "therapy."
