"Horribly written" is blunt criticism, like it or not. The parent post is saying that because you delivered blunt criticism, you should be prepared to take it too.
If you actually read what I wrote I said "This seems to be horribly written." Note the word "seems" that is not the same thing as saying "it is." I then go on to ask a question for clarification which some folks were kind of enough to point out helpful and corrected interpretations. Asking a question and admitting something wasn't making sense to you are not at all the same thing as "dishing out criticism."
