That day isn't today, and until it is, worry is reasonable. Look at the several precedents offered in this thread.
My point was to continue the fight. We can take this legislation, work to get the language removed and if not work, make sure ammuntion isn't banned in another bill. We can't work for that bill if we don't have a clear pro-gun majority. If we had 80 milion gun owners working for it, we can make it happen.
Join the NRA, call your legislators and activate those gun owners who aren't doing anything. You can worry on another day.
