I hate this person, I hate them with all my heart and I don't know if I can forgive them?

Wait - you are saying you 'hate' this person, whom you don't even know, because they made a bad parody of a Dr. Seuss story? Are you for real? You might be in shock, but I doubt very much you 'hate' this person, as that emotion does not come into play for light a reason. As far as 'forgiving' them... there is nothing to forgive. You need to forgive Yourself for allowing yourself to get so emotionally distraught for such a trivial and unimportant thing.
