Yes, I think this is something that his happening here. It's at least partially my fault, because once I had to pull the review into Gist, it was easy to post it on Twitter too, and so it took on a life I hadn't anticipated for it.
I don't think you're at fault for anything. There's nothing inappropriate in your review.
It's ridiculous to simultaneously say that a piece of writing devoid of context is being classified in a certain way and to say that it contains that's inappropriate for that classification.
The mere presence of phrases like "I am not making this up" tells you that this piece is not intended to be too serious. To say that it's intended seriously but contains non-serious language is a flat-out contradiction.
It could make sense if it was published in some context, like a serious blog or a news site or something, which implied seriousness. But it's a naked text file on the internet. It doesn't have to take a serious tone.
