Very less can be done about people who do such things, there is no central authority that controls such impostors. ''Its Free country'' phrase like Americans use.
Those who are rooted into true fertile earth of Hinduism will hardy worry about whats going outside as they know nature loves symmetry and anything odd, false and asymmetrical will perish sooner or later.
Those who worship such false Gods will either learn their lesson or may die worshiping these thugs.
People think it bring bad name to Hinduism then yes I does, only for people who do not understand Hinduism.
Making Hinduism perfect will have a toll on many things including its very basic tenants of tolerance, not to mention it will warrant a dirty fight with these pigs rolling in muddy sewer. The ultimate winner of this fight will be outsiders who will make there own case strong for themselves in either case.
btw Such impostors are found in very religion, few are more clever than many crude, like shemale above in question.
An argument can be made that one has to get his hand dirty to fix this menace but I see Hinduism as steadfast it was during vedic times. Hinduism is open book anyone can come and learn it and interpret, practice or plagiarize the way he or she wants.
Also there is no lack of examples when such people and practices where fixed, even Mahayudhas were fought to bring sense back in the society. That option is always at the bay.
