Boy oh boy, I think I could give you about a dozen reasons why the left hates gun shows. This is a fabulous topic, IMO, well worth discussing at length.
You stated one of the more important ones; Centers of organizational energy for Constitutionalists. That’s of course a double-—they hate the Constitution, they hate the idea of “the other side” organizing for anything that isn’t what they organize for, since anyone who disagrees with them is a knuckle-dragger. All kinds of fear and revulsion there.
But there are a lot of other reasons, both subtle and profound.
Here are people exchanging their money, the fruit of their labors, for which they have exchanged their time, their finite resource. And they are choosing to trade their money (which isn’t really theirs to spend as they wish, only the highly-educated elites can conceive of societally-justified progressive avenues of spending/directing money) in an exercise of their freedom. Well that’s bordering on a trifecta. Only the elites can know who should get this odd thing called freedom; And it’s God-given...there being no such thing as God, that right simply cannot exist. And so if out of this warped sense of freedom, these folks exercising their freedom (to spend their own money and to bear arms) make the asinine choice to buy a killing tool, then those societal outcasts must be looking to kill something or someone. I mean, nobody buys a screwdriver unless they have screws to turn or paint cans to open, right? Therefore these losers must be looking, desperately, to kill as many things as they can, whenever they want. This has to be stopped at all costs! Society cannot allow this to go on! Nobody needs to kill a sweet little deer when they can 100 times easier go down to Safeway and buy a steak and it’s wrong to eat meat anyway. Why don’t these gun nuts just take their money and go buy their food at Safeway?
I could go on, but I am a little pressed for time at the moment.
Very fruitful nexus of discussion.
The liberal cannot stand seeing people enjoying themselves doing something they don’t care to do.
