Nah, it just means that they either tried desperately to deny their urges and fit in with society because people that hate gays often make their lives hell, or that they simply were able to push beyond their distaste in order to have a child.
The reality is, most of the children that live in the situation you want to "save" adopted children from by simply not allowing them to marry are the natural children of one of the homosexual "partners", are not abused, and are protected by the laws already in place for that purpose.
