The main problem is not that that Nico is gay but the fact that it came out of nowhere. There were no hints about it prior to The House of Hades, which means the author probably just came up with it while writing the book, and by doing so shocked a lot of the younger readers.

And JK Rowling was attacked by the same conservative parents that now attack Riordan. They claimed that the HP series taught children "witchcraft", whatever that means.
