‘Conversion therapy’ is homophobic and dangerous. Yet it threatens to make a comeback | David Kirp

Bans on the dangerous practice, condemned by national mental health organizations, could soon be struck down

Homosexuality is an illness that therapists can and should cure: that's the rationale for conversion therapy", a practice promoted as a way to change an individual's sexual orientation from gay to straight.

But a host of studies conclude that such counseling doesn't work - small wonder, since sexual orientation is a core part of an individual's identity. It's also potentially harmful, especially for minors. Research shows that youth subjected to conversion practices, often at the insistence of misguided parents, are prone to depression, anxiety, drug use, homelessness and suicide.
