I have a perspective on this poem that I don't think other reviewers can replicate, but I'll need to wade into idiosyncratic waters. So here goes:
I think reasonable people could misinterpret this poem.
Let me get straight to the point. This:The real monster is he who stays up late
Writing false doctrine for spur man's hate
Xenophobia is his unfathomable prattle,
On my first read, didn't parse with this:To an untrained eye he might look normal,
A face like yours and a suit most normal
That's because I've personally seen those last two lines's sentiment used against inclusiveness. That comes from personal experience; I've lived my entire life with involuntary-commitment-level panic attacks (also known as "you're fine, stop being dramatic"). My outward normal-ness, while its given me a good deal of privledges, makes people suspicious when they learn about my mental health. From the way these two lines are phrased, this poem might be lumping me in with the xenophobes...
...but after some self-reflection, I think I'm fine with it? Actually, I like it? I really like it?
I read this poem, had a knee-jerk bad reaction, and then slept on it. And then I realized this poem about not liking something felt negative because it's a poem about not liking something.
Not only that: I don't think this poem is just negative. Your third stanza, where you liken Lovecraftian horror to real tragedies; that's a great metaphor! Cthulhu devours your brain or you get shot in the head; you're dead either way. And it encapsulates the difficulties of facing real-life horrors perfectly.
But more than that, your third stanza made me angry. Lovecraft was inventing fake horrors when he could be using the real horrors of life, and he didn't. And that tells me a lot about how Lovecraft viewed the world, what his perspective was, how little he knew of tangible horror. At best, you could say he knew existential dread. But a quick lookup on Wikipedia shows he had other views:
said:
From the start, Lovecraft did not hold all white people in uniform high regard, but rather esteemed the English people and those of English descent.[112][113][114][114] He praised non-WASP groups such as Hispanics and Jews; however his private writings on groups such as Irish Catholics, German immigrants and African-Americans were consistently negative.[115][116] In an early poem, the 1912 "On the Creation of N*****s," Lovecraft describes black people not as human but as "beast[s] ... in semi-human figure, filled ... with vice." In his early published essays, private letters and personal utterances, he argued for a strong color line to preserve race and culture.[87][112][113][117] He made these arguments by direct disparagement of various races in his journalism and letters,[80][87][112][113][114] and perhaps allegorically in his fiction concerning non-human races.[103][112][118][119] Some have interpreted his racial attitude as being more cultural than brutally biological: Lovecraft showed sympathy to those who adopted Western culture, even to the extent of marrying a Jewish woman whom he viewed as "well assimilated."[87][112][113][119] While Lovecraft's racial attitude has been seen as directly influenced by the society of his day, especially the New England society he grew up in,[112][113][114][120][121] his racism appeared stronger than the general popular viewpoint.[114][119]

I've read your previous poem; since I already knew your identity, I don't think my knee-jerk reaction was reasonable. I do worry a reasonable person could misinterpret this poem, as this poem was posted standalone and doesn't reveal your identity. You could remove the two lines I mentioned, but I think that'd sap away at the poem's sense of anger (from my experience, if someone's really mad, you should expect collateral). I think the best step would be to put your two poems in a collection, with your previous poem on top. Or add something to the text of this poem that explicitly reveals your identity, giving context for anyone who doesn't already know who you are. Or even just a short author bio as a before-poem summary. It's a small thing, but remembering your identity made a world of a difference to me.
I like this poem. A lot. More than your other poem, actually. Your previous poem only had nitpicks, flaws so minor they didn't warrant words. Why I Don't Like Cthulhu is less polished, more flawed, but also cleverer with its metaphors, rawer with the emotions. Thank you for sharing this; keep it coming!
