PA State Firearm?

A state senator in Pennsylvania wants to pass legislation naming the Pennsylvania Long Rifle as the state’s official firearm. Report here.
While I think that such legislation is silly, I otherwise don’t have any objection to it. Some, however, do:

[O]opponents say the idea of designating a state firearm is unthinkable, especially since Pennsylvania cities are scarred by gun-related crimes.

Said opponents are not named in the article, nor is their reasoning — such as it is — explained. How does naming a historical, blackpowder, single-shot, longer-than-four-feet-long rifle as the state’s official firearm have anything to do with violent crime? Whoever these opponents are, they need to unbunch their panties.
