Reparative therapy as a broad-based effective treatment has been debunked. Can a couple individual people theoretically benefit from therapy? Who knows. But as an industry, in which one would expect gayness to be cured, it is debunked. And it has been proven to cause pain, trauma and damage in the many for whom it did not work, as jfem mentioned. In response to ubiq, you did say it was curable by saying that therapy works.
“This parade is not a show pf solidarity with people struggling with these issues neither is it a protest against discrimination, as some posters have tried to claim.
This is parade to celebrate this kind of lifestyle,( this is who I am and im proud of it) hint, it lies in the name.”
You’re conflating two issues. People being gay and people engaging in homosexual activity. It is very likely that someone who has this struggle might want to identify with others in a similar situation in solidarity. While one may not have to feel pride, theoretically, one need not feel shame either. Sinning, of course, is another matter. While the parade does celebrate homosexual activity, and is therefore not hashkafically or halachically correct, it’s not beyond the pale for people to feel solidarity solely on the identity part. And that’s not a sin. But lifestyle and identity are two vastly different things here.
