The idea of pink guns (or any other color) is not a new idea. Nor is the idea
of pink hammers, drills, tweezers, kitchen knives, or any other tool. It is
marketing nonsense designed to extract additional money from the wallets
of those unable to discern (or who buy on impulse).
The people who would comprise the market for such objects are people
who, in my opinion, never really wanted/needed the object in the first place,
and would stuff it in the back of their closet and forget about it. It sounds
like a fad to me, like parachute pants, and will be gone 2 years after it
starts.
Who the heck would want a pink gun in the first place? The women I know
would be really turned off at the idea, and might even view it as insulting.
