I guess it's inevitable that the level of protest and violence that happened in the wake of the publication of the satanic verses would have a chilling effect on the publication of books that might be deemed sacrilegious by fundamentalists.
I was thinking the protests around Drag Queen Story Hour are likely to have a similar effect - the tour that's currently happening will grind to its end, but the bookers in libraries will pass next time when they're looking for nice events for kids over the holidays, because it'll bring with it a high chance of a load of freaks screaming 'paedo!' Outside their library.
People - and particularly corporations (and council libraries) are risk-averse is what its down to. I'm not sure what the answer is though- you can't really blame authors for choosing not to write novels which might get them stabbed by religious nutters, or publishing houses for choosing not to publish books that might get their translators murdered etc.
