There's an obvious difference between one who genuinely suffers from aerophobia and one who is nervous to fly on Malaysia Air, let's say, shortly after two of their planes crashed. You might disagree with the hesitant traveler, but to him, several recent mishaps or malfunctioning jets are a rational cause for concern, even if those mishaps represent a tiny minority of flights.
Perhaps it's similar to how I might be singled out for scrutiny if I were to tell the airline people that someone else packed my bags. Security personnel might react to unaccompanied luggage or bag (what they call “חפץ חשוד” or suspicious object in Israel) with similar alarm. Let’s be honest that there’s valid cause for concern, even if the vast majority of such bags are harmless.
Instead, I'll realize that you are simply suffering from a "freedom-of-opinion-'phobia,'" an irrational fear or aversion to hearing views that differ from your own. This psychological disorder is often induced by excessive media consumption or unprotected college-campus indoctrination. Highly contagious! The most obvious symptom of this condition is when you regard any view that differs from your own as "irrational" and consequently diagnose it as "phobic."
Just kidding. I realize that you are most likely using the term "phobia" in a pejorative sense in attempt to belittle anyone who disagrees with you.
