Every trumper is a N4T.
Grammar and punctuation exhibits an individual's intelligence. You are proof of this.
If you possessed the grammatical skills and intellect you imply that you do, you wouldn't have put an "s" on the end of "exhibit" because you were talking about more than one thing.
Example:
Grammar exhibts an individual's......
Punctuation exhibts an individual's......
Grammar and punctuation exhibit an individual's......
Lesson: Don't preach at others about that which you are not an expert on yourself.
Have a nice day.
