My understanding of any 'risk factor' is that it is one of many. I think that promiscuity is a major risk factor. So is a low sense of self-worth.   And my guess is that the acceptance of the reality of a person's sexual orientation and helping them do what they need to do to increase their own self-acceptance---whether that be through pride parades, legalization of gay marriage, etc. is going to significantly reduce that risk factor.

And the reality is, GFS, that the attempt to change a person's orientation has only reinforced that one's sexual orientation 'should' be changed.   There are no 'shoulds'. Any more than I think that your opinion 'should' be changed.   Personally I'd like it to be changed. But that's my thing.    It is what it is.

As well, I think that most people have accepted that trying to change an orientation that a person has had since birth (or even before) is an exercise in futility......for most.

Sorry if this has already beeen posted, but you may want to take a look at it.

Michael Busse (co-founder of Exodus), Darlene Bogle (a former Exodus ministries leader), and Jeremy Marks (former Exodus International and head of Courage UK) issue a public and formal apology for their work as ex-gay leaders and the harm they caused to those they tried to help.
