It could, certainly.
But before it gets to that point, a repeal of 2A first has to pass a majority of the convention to get proposed as an amendment, and then it has to pass the legislatures of 38 states to become an amendment to the Constitution.
Are you ready to have a serious discussion on the likelihood of this happening, given that Obama couldn't even get gun control legislation passed in the Senate after Sandy Hook?
It seems to me that people are tossing out bogeymen arguments that on their own merits don't pass the reasonableness test. People are only here to scare.
