He thinks kids go on YouTube or Tiktok looking for cool sneakers and are somehow bombarded with content about eating disorders or bullying. My guess, though, is that it's more like if you look for content on those topics, the algorithm will serve you more of that. Which could be good or bad, depending on the situation.
In any case, it's nigh impossible to legislate "show people LGBTQIA+ content if they want it, but don't serve it up to them algorithmically." Like, that's not how anything works.
