If I were one of them, wanting to ban all "cool" guns or most of them but not knowing wtf I was doing, I would put out something preliminary, then lurk on sites like this as informed folks discussed the loopholes and workarounds, then that would give me a start on tightening up the text.

Sorry, they may be ignorant but they are not all stupid.

And if we shut up about things here, there are 100 other sites that knowledgeable people use that they can troll and lurk on.
