hoplophobia
The irrational fear of guns.
uncountable
Gun control laws are proposed to control three basic areas: Crime, accidental shootings, and to calm those suffering from hoplophobia — these people generally align themselves with the first two so I won’t even consider that category.
Where it comes from
Firearms authority and writer Colonel Jeff Cooper claims to have coined the word in 1962: hoplo- (“weapon, arms”) + -phobia (“fear”).
