Tens of thousands of American LGBT kids are subjected to ‘conversion therapy’ before they hit 18.

An estimated 20,000 LGBT children in the US are subjected to conversion therapy from a licensed health care professional before they turn 18, claims new research.

Conversion therapy is an effort to change a person’s sexual orientation or gender identity and is grounded in the belief that being lesbian, gay, bisexual and/or trans-gendered is abnormal.
