And if I was a betting man, which I am, I would bet must people would not have a comprehension issue with that level of grammatical error. Most of the things people get but hurt about are simple typos. Most people know the difference between your and you're they just mistype the word. Happens with lots od words that sound similar. Double negatives and poorly structured sentences do cause confusion but too vs to. The break silly rules like saying you and me instead of you and I because outside of a few lit majors and some grammar Nazis they simply don't care.
