Homosexuality, transgender identity and other non-heterosexual orientations or gender diversity continue to be seen as illness or sin in many societies. Conversion therapy is a practice that aims to change, cure or repair an individual’s sexual orientation or gender identity and it is a global problem that causes severe physical and psychological suffering to its victims. According to a research it is found that conversion is is done in more than 69 countries in all regions and the practice is undertaken within adults and even minors too who may be gay, lesbian, bisexual, trans and gender diverse. Due to the difficulties faced in the therapy it is globally banned now. This practice violates the basic human rights of the individual. This therapy is illegal, cruel and inhuman. We have seen that conversion therapies can lead to avoidance behaviours, hypervigilance, intrusive flashbacks, traumatic nightmares, and other symptoms. Conversion therapy is both provided under state and in private. There is no 100% guarantee that conversion therapy in any form can be effective and that any treatment or practices that can change an individual’s sexual orientation or gender identity lack any foundation in science and medicine. Conversion therapy is a form of discrimination and repression which harms victims and may further isolate them. Many acts of conversion therapy bear strong similarities to internationally acknowledged acts of torture and other cruel, inhuman or degrading treatment and punishment. Children and minors are particularly vulnerable with a sharp increase of suicidal tendencies in those who have gone through the treatment of conversion therapy. It needs to be stopped. Government should completely declare it illegal and whosoever does this should be punished.
