LONDON (Thomson Reuters Foundation) - An Irish lawmaker has introduced a bill that would ban so-called conversion therapies claiming to “cure” lesbian, gay, bisexual and transgender (LGBT) people.

Fintan Warfield, a senator with Irish nationalist party Sinn Fein, proposed the bill on Wednesday to ban conversion therapy as a “deceptive and harmful act or practice against a person’s sexual orientation, gender identity and, or gender expression.”

Despite global gains in LGBT rights, many gay people are still forced to undergo archaic and invasive therapy based on the idea that homosexuality is a mental disorder or medical condition.

Although conversion therapy has been widely discredited, only Brazil, Ecuador and Malta have nationwide bans, says the International Lesbian, Gay, Bisexual, Trans and Intersex Association (ILGA).

Such therapies could have a “negative impact on people’s mental health, as they can lead to lower self-esteem, depression and suicidal ideation,” Evelyne Paradis, ILGA’s executive director in Europe, told the Thomson Reuters Foundation.

“Legislation sends out a powerful message that stigma masquerading as ‘therapy’ will not be tolerated by modern societies ... and we encourage Irish parliamentarians to quickly pick up this really important issue,” she said by email.

Under the bill, individuals found guilty of performing conversion therapy on another person could be fined up to 10,000 euros ($12,351) and face up to a year in prison. Read more via Thomson Reuters Foundation
