It can actually only be called “misleading” if it was the author’s deliberate intention to mislead the audience. If the author had no intention to lead you to the wrong conclusion, and you simply arrived at one all by yourself, it’s just sparkling Your Lack Of Reading Comprehension.

If one text is incomprehensible, the author may be lacking writing skills. If all text is incomprehensible, you just can’t fucking read.
