Hellenomania [actually, this should be Hellenologomania]: 1. Said to be an impulse or tendency to use complicated, cumbersome terms, frequently Greek or Latin, instead of what is considered to be readily "understandable English words".
Dr. Robert J. Campbell in his Psychiatric Dictionary says, "The impulse is rampant in the field of psychiatric writing, as witness the list of (generally undesirable) terms under fear of."

hemaphobia, haematophobia, hematophobia, hemophobia: An abnormal fear of the sight of blood or of transfusions.
Phobics of blood may recoil, close their eyes, or even faint when faced with the sight of their own or another's blood. Victims of this phobia may experience more nausea and faintness than fear or anxiety. With hemaphobics, there is often a sharp drop in heart rate and blood pressure.

When the natural mild fear of blood or injury is magnified to phobic severity, it can lead to substantial handicaps. Sufferers may avoid essential medical procedures, preferring to endure a remediable disease even if it threatens their lives. They may also avoid otherwise attractive careers as doctors or nurses.
heresyphobia, heresophobia: An excessive fear of challenges to official doctrine, or a fear of radical deviations from the "orthodox" view.

Without Contraries
is no progression.
Attraction and Repulsion, Reason and Energy,
Love and Hate,
are necessary
to Human Existence.
-William Blake, English poet, artist
He who hath been bitten
by a serpent is afraid
of a rope.
