Not understanding the 5th nullifier set by Muhammad ibn abd al Wahhab

As per the 5th nullifier, it states that "whoever hates something that was brought by the Messenger (blessings and peace of Allah be upon him), even if he complies with it, is a disbeliever." but how can it be if that hate is naturally instilled in the heart and is a natural taste/preference of the individual? I perfectly understand that ridiculing or crticizing outwardly is kufr, but I don't understand how can a person become a disbeliever if they hate (parts of) the Sharia despite of them forcing themselves to comply with it? Shouldn't the attempt and the effort be rewarded instead of one's inclinations of preferences? I mean, what if Allah (swt) created that person that way? How can it be their fault for a characteristic that does not depend on them in the first place? I can understand if the disliking translates into action only, but not otherwise as long as efforts are made.
