I read this a few months ago and just came away with the slightly soiled feeling of having spent several hours in the company of a quasi-incel who has an extremely unhealthy attitude towards sex. It's not even that he's writing from the viewpoints of teenagers and sexually repressed people, it's just a constant screed. I ended up siding with the pro-castration characters.
However, I will say that the opening sequence in the cathedral is a brilliant piece of AH exposition, in that you can almost get through the whole scene without clocking that it's AH if you're only skimming it, but if you pay attention and you know your art history, you can piece together quite a lot of the worldbuilding. I wasn't a fan of the shoehorned Dick reference, it felt a bit too look-at-me and didn't quite make sense - however, the more subtle references generally work.
