That's the argument made by Jason at this Delaware Liberal post.
What on earth gives anybody the right to buy 20 guns per month?
You are a bunch of dnagerous morons who I am done dealing with.
Yes. Because they are selling them to criminals stupid.
I've got to say that DL is fast becoming my favorite moonbat site, not only because of the nutty and juvenile arguments (such as those above) often found there, but also because the regulars don't seem to be the usual fit-us-all-in-a-phonebooth-and-still-have-room crowd you can find at other leftwing sites. There's actually some decent debates and a wide variety of opinions expressed (the thread that the above comments were taken from actually contained some interesting arguments for and against gun ownership).
Admittedly, Jason did offer a nonapology yesterday for his churlish behavior. But that just made the whole reading more entertaining.
For the record, I don't care how many guns you wanna own as long as you use common sense when using or storing them. You know, lock 'em up so 3-year-olds aren't going to find one under the bed and shoot Grandma with it. But other than that, if you want to own 50 guns, that's fine with me.
