"I would like to know how hard is to leave the organization."
it is really quite easy...
you decide you cannot be involved
with an organization that is as judgmental
as the b0rganization happens to be....
they dont have the Truth tm and never did
eventually, one way or another, you will find
a community that accepts you for who you are.....
even churches in the realm of Xianity are starting to
make inroads into acceptance of variant expressions
of human sexuality.... many are becoming what they
cal RIC (reconciled in christ)..... so you do not have to
forego xian association, if that appeals to your sensibilities
