Many deaf people have poor grammar because American Sign Language (ASL) greatly simplifies and, in some cases, omits things that are not really needed to convey an idea.
To a deaf person subtitles are is overly verbose and the word order is strange (for example, subtitles has "running," which is the word "run" followed by a sign for "ing." ASL does away with "ing" because it is obvious in context).
