They'll take them if the people don't stand Up for their rights. But they wont go door to door and take them. Theyll just mandate that you turn it in or offer a buy-back program, and people will just dumbly comply. Other countries like New Zealand, Great Britain, and Australia have successfully taken them away from their citizens Due to their apathy.
Well so far the only people I've heard talk about taking guns away are people who bring up the point just to tell you that they will never give their guns to the government.
Its a ludicrous idea on the face of it- who the fug is gonna pass this law, congress? Haha, right. Republican congressman couldnt even consider the possibility without being immediately replaced, and even if a bill gets forced through congress it would be thrown out by the supreme court so quickly it would make your head spin.
There is absolutely no need for you to "stand up for your rights" on this issue- you already have one of the biggest lobbying groups on capitol hill doing that in a far more effective way ($$$$$)
