I can't say I don't understand their point of view. The problem is that all the accusations they use, which the majority use, are refuted by an immutable fact.
It's fiction, it's not real, it's drawings, pixels, polygons, etc. It's not real.
And of course, you may like it, dislike it, be upset, whatever you want, but the point is clear and concise: it's not real. No one was harmed or pressured to create such content. Chasing it is a waste of time because at the end of the day, no crime was committed. That loli isn't a person, those siblings aren't real. All those taboo, violent, or in some cases, criminal scenes never happened, because it's all fiction. And criminally pursuing fiction is dangerous because there's no limit. If something fictional is illegal, everything fictional is illegal, even your imagination.
Meanwhile, in the real world, there are real crimes, real victims who need help, support, a voice so they can find justice and bring closure to traumatic moments... but nobody gives a shit, because it's not media-friendly. Who cares if a 12-year-old girl was raped? Saying we shut down a loli game, got it removed, and put its creator on trial will attract more attention and more revenue.
It's basically PETA.
