3,5 stars.
First of all, a breakdown of how the stories inside this anthology fared:
The Good: The Bread We Eat In Dreams, Six, The Nazir, Ghostweight, How To Talk To Girls At Parties, Give Her Honey When You Hear Her Scream, The Horse Latitudes, Never The Same, You Go Where It Takes You, Dream of the Fisherman's Wife
The OK: Dead Sea Fruit, Muo-Ka's Child, A Handful of Earth, If You Were A Dinosaur, My Love, Boyfriend And Shark, Terrible Lizards
The Meh: Tasting Gomoa, In Winter, Mantis Wives, Out They Come, Theories of Pain, And Love Shall Have No Dominion
Scarred me for the entirety of my existence: The Emperor's Old Bones, The Things, Night They Missed The Horror Show, Proboscis
I think the really excellent stories belong to the fourth category. I really enjoyed Emperor's Old Bones and the twist made me scream internally (lmao) and that ending is perfect, I also always enjoyed the entire "criminal protag" trope so maybe I'm a bit biased. The Things is, hands down, the story that best represent the theme of the anthology and it's some top-notch mindfuckery. Night They Missed The Horror Show is just plain fucked-up and a little bizarre, while Proboscis is straight-up r/shortscarystories body horror (thankfully off-screen or I'll never sleep ever again). I think my fave is tied between Emperor and Proboscis.
Let's be honest, though: this anthology draw me in because there's a Neil Gaiman story in it. I was a bit disappointed because it was a story I've already read a million times before (although I still love it). Overall, it's pretty good, but it just doesn't quite live up to its grand overarching theme. I had to commend it on the diversity of the contributors, though, which...actually made me pretty afraid at first because I fucking hate forced diversity (and the fetish that the far, "progressive" Left seemed to have with it), but the entire thing actually came out pretty decent and enjoyable, the stories were fairly engaging (and disturbing, let's be honest), and the characters were well-written, including the LGBT characters. Kudos to that.
But I think the arrangement is kind of...funky. I've read quite a fair number of anthologies before, they were usually organised based on how good the story is and how famous the author is, at least from what I've observed. The last spot is usually reserved for what is considered to be the crown jewel of the anthology. However, The Humanity of Monsters doesn't really work like that, and it actually made me confused as to how the stories were actually organised. There were really good stories in the middle and there were meh stories in the back. I think it could fare better with a proper organisation.
This anthology also got off the wrong foot, in my opinion. True, the editor stated that this anthology dealt with the problems of "Othering" (I actually won't use the term Queer, because as a trans, bisexual individual myself I have problems with it), but I strongly feel as if the anthology could have started with something fantastical, and then broached the actual social themes later on. Tasting Gomoa doesn't make me feel as if I was reading an anthology about monsters, it makes me feel as if I was reading a lesbian erotica fanfiction on AO3. And it makes me think that it was probably placed there, intentionally, as a shock value for straight people. Which is not necessarily a bad thing, but it doesn't really humanise the bisexual protagonist and thus lead off with the tone that LGBT people are the "real" monsters. Maybe I'm just salty because I don't really like the story either (feels flat and forced and hurried to me, I'd enjoy a little more built-up between the protag and Gomoa), but I really think that the opening story (and as I said before, the placement/organisation of stories in general) could be something better.
I do love the fearlessness, the candor of the stories, though. They're not afraid to be graphically disturbing, they're not afraid to shock and awe and traumatise, to turn things round on its head, because that is the point of monsters. If a monster is a warning, then what good is a monster who can't scare you senseless? I think this anthology managed, at least, to capture and demonstrate that monsters can manifest in a lot of different ways, that they are more intrinsic to our lives than we initially thought. All stories are about wolves, after all.
In the same vein, I think what the editor said in their foreword--about this anthology being about the liminality of state--is true. This is something that this anthology has managed to achieve, for me. Where does man end and monster begins? On the reverse, where does the monster ends and man begins? This is something writers have been asking themselves for a long, long time.
Overall: This could be better, but the same could be said about many things. At the very least, this is quite entertaining, disturbing content aside, and some of the stories are very good. I wouldn't exactly recommend this, and it doesn't quite fulfill my expectations, but it's not bad, either.
