It is the trauma of homosexual rape or seduction in the pre-adult years that induces same-sex attraction disorder.
Of male homosexuals who claim not to have been raped or molested prior to “identifying” as homosexual, 100% are lying.
A few psychiatric professionals share your conclusion that it is 100%.
Many memories are suppressed and indeed some aren't recalled until much later in life (30s).
Several of these late recalls of same sex molestations are in fact hetro.
To be sure, molestation itself is NOT determinative of life behavior.
