I don't understand the point you wish to convey. Do you think the claim of either OP or the article is that queer people are pedophiles? The article talks about how this story has been opportunistically exploited by fascists, here are a couple of excerpts:

Schweer had “offered help from the AfD,” Marco told me. “I immediately said, ‘Not for political purposes, only because I want help.’ ”

From the perspective of an AfD politician, Marco’s life story was expedient, a tale about the ways in which the German left had got sexual politics wrong. At meetings of the German parliament, members of the AfD (which won more than twelve per cent of the vote in the last national election, becoming Germany’s third-largest party) rallied around the Kentler case as a way of forcing left-wing politicians to address history that did not reflect well on their parties, but also as a barely disguised vehicle for impugning homosexuality. An advocacy group affiliated with the AfD held “Stop Kentler’s sex education” rallies, to protest the way that sexuality is currently taught in German schools. “Kentler’s criminal pedophile spirit lives on unbroken in today’s sex education,” a brochure printed by the organization explained.

Later:

Christoph Schweer, the AfD adviser, had urged Marco and Sven to keep fighting, but Marco couldn’t understand why. “We have gotten our wishes, so there’s no point in further irritating or tyrannizing the Senate,” he told me. But Schweer kept pushing him, Marco said. (Schweer denies this.) “Then I slowly got suspicious. I asked myself, What else should I want? That’s when I got the feeling that the AfD just wants to use me, to play me up. And I said, ‘I don’t want to be a political tool. I don’t want to get pulled into an election campaign.’ ” He dropped his lawsuit and accepted the Senate’s offer. His only remaining goal is that, in the upcoming report, all the names of people involved in carrying out Kentler’s experiment be revealed. (Schweer said that he had been supporting Marco as a “private person,” not on behalf of the AfD. He also told me, “I have new ideas, but for [Marco] it’s over.”)

I'm not getting it, this is bad right? Like putting kids with pedophiles who exploit them and then protecting the pedophile's power over the kids is bad?

I can get if this specific thing is used out of context to denegrate queer groups, but it's also something that you shouldn't be dismissing and instead being very vocal about the fact that this is exactly not what being queer is right?

This type of exploitation also actively harms people in those communities since it seems like the idea was to push kids who were already at risk into situations where they were being actively exploited by pedophiles...
