And how is that proveable? One homosexual experience? No past heterosexual marriage? No past heterosexual experiences? A chosen lifestyle? A transgender attempting to engage in a "heterosexual" relationship when the partner is the same gender as the birth gender of the transgendered person? Is there a blood test for homos, for heteros? Brain scan? Maybe they can watch porn and see what turns them on. If it's two women in lesbian acts and you're male you're a red-blooded heterosexual American.
It is on the application form. If you lie on the adoption paperwork the adoption is VOID (not voidable, void as in it does not happen)
This may seem technical however the documents are under oath and penalty of prosecution. There are also the home studies, and other aspects. It is not the drivethrough at McAdoptions.
this is no differnt than INS applications which seem to ask absurd questions but are really traps for revoking a persons visa in the event of a lie.
