Have a feeling that being brutally gang raped is not going to make these women renounce their orientation -but will make them hate and fear men, if they didn't previously. These 'men' use the fact that they are gay as an excuse to brutalise them.
Since the gobment won't do anything, said women would be wise to take things into their own hands.
Lesbians don't need to be cured. Instead straight birds need to be converted into lezzers, more to watch and all that. "Do you take this man to be your lawful wedded husband and do lezzie things with yer lez mates for him to watch?"
