I have transcribed and translated the part of the broadcast:
"In Bethel, Alex continually fights his demons. Despite hard work, prayers and preaching, he is unable to deny his homosexuality. In desperation, he finally confides in an elder.
Alex: “He then advised me to get in touch with someone who was also at Bethel. He said: “He has the same problem as you.” And then he actually told me: yes, he's currently undergoing therapy, conversion therapy, to be cured of his homosexuality. It would be nice if you could do that too, because it would really prove that you are serious and that you really love God, and he will help you and support you so that you become normal. And then I was so desperate and depressed at the time that I thought: “Yes, then I'll just do it.” And then we always went to Poland. Poland, why? Because it's forbidden in Germany.”
Reporter: “I'm shocked right now that Jehovah's Witnesses assume that homosexuality can be cured.”
Alex: “Not a single person who took part in this therapy was cured of homosexuality. There really were Jehovah's Witnesses from all over the world. There were some from America, from Great Britain, from Germany, from Poland. And all those who simply have this pressure of suffering take on these costs and these efforts and all this stress just to be cured. But that made me feel worse and worse, and in the end I was very suicidal.
Expert: “Conversion therapy claims that it can change a person's sexual orientation. This is a very dangerous claim for many reasons, because we know scientifically that people's sexual orientation cannot be changed. Furthermore, homosexuality is not a mental disorder, and we know that such offers can have very negative effects. These people who take up these offers and really believe that they can change their sexual orientation typically find out when they come to terms with themselves that what they are promised does not happen at all. And then they have the impression that they are doing something wrong because they don't realize that the offer is already dubious.”
When Bethel realized how badly Alex was doing, they sent him home. It was clear to him that he had failed as a Jehovah's Witness. Traumatized, he returns to Stuttgart."
