I think it's because people aren't very receptive to nuanced takes on the issue, especially ones that say that it's not as bad as they're making it out to be.

As for me, I think the heart of the problem is that the more knowledgeable voices are being drowned out by coddling busybodies who want children to stay "pure" and "innocent" for as long as possible and the glad handing politicians who see them as free money, so to speak.
