Side X:  

These folks do not embrace same sex attractions and
thus they seek to change their orientation.  

They typically believe that their same sex attractions are
tied to an emotional disconnect with one of their parents.  
Many also report they were sexually abused at an early
age sometimes by a same-sex individual.   

As stated before ... there are heterosexuals that have
experienced these same types of things but it did not
create same-sex attractions.  So this may be unique to
certain people.
