Yes, I'm conflating them for dramatic effect, perhaps unfairly. If MMA is on fire, it will produce acrolein, and a lot of other chemicals as well.
I've known people who've died from both, separately, as well as ethyl acrylate and acrylic acid. I've gotten a few bursts of them in the face as well, luckily nothing too awful. I'll repeat that acrylates in general are truly awful chemicals to be exposed to.

And that's exactly the sort of thing I'm objecting to. Conflating things for dramatic effect is also known as "lying".

Citation needed. It burns hot enough that in open air the vast majority of the carbon will go to CO₂ or CO. Oxygen starved, I'd expect the hydrogens to burn off leaving soot. There may be some trace amount of acrolein, but that's true of cooked food too.
