As do many boat owners with their boats, many gun-owners call their handguns "SHE". Some even name them.
Associating beautiful women with handguns works for many. Anti 2A-types, might call this an emotional attachment of a nut with a gun. Would the boat-guy be a nut with a boat? I too call some guns 'Pretty' or even 'Beautiful'.
Anyway, I can see where trying to make this same type of association with the serious 2A amendment assaults facing American citizens,
could be looked at as downplaying the seriousness of this RIGHT under the Constitution. I doubt any of us here think a lighthearted issue at all.
The author has the 'right' to printing the cover of her serious subject book as she did. Here we are discussing it. It works. Pretty, usually generates a second look, even with old guys.
It also shows that not JUST "male nuts with guns" have the right to defend themselves.
No harm, no foul.
