Can you name two of those dipsticks? I don't think you can, and the truth is that the one you could name is not accurately described by your comments.
Of course we all understand that target shooting can be fun, and you don't have to be some sort of psycho to enjoy it, and you aren't practicing for killing people. Yeah, someone said something that was kind of sort of like that, but, really, he was just trying to make a completely different point. In reality, I don't think a single person who has contributed here thinks the way you have described.
I don't think you could find 1 out of 100 Americans who would make it impossible, or even difficult, to go skeet shooting, and I don't think you would find 2 out 100 Americans who would look down on anyone just because they do it.
If the effort to restrict firearms continues, to the point that politicians actually pass legislation, we will all have to deal with this sort of mischaracterizations, I know, because that's really all you've got. The slippery slope argument is the only one that could possibly carry the day when it comes to private ownership of military capable weapons.
Not all slippery slope arguments are instances of the slippery slope fallacy, but most of the ones employed against gun control are. Anything that says that if we forbid the manufacture or sale of assault rifles, we will next forbid handgun or hunting rifle sales, is a slippery slope fallacy. Anything that says registration will lead to confiscation is a slippery slope fallacy. I expect to see a lot of them in the near future.
