I really don’t have a problem with liberals attempting to repeal the 2nd Amendment as long as they follow the path laid out in the Constitution. Where I have a problem is when they try to redefine what the 2nd Amendment says, ie, collective right protecting the national guard rather than RKBA.
However, most liberals will tell you that they think amending the Constitution to remove the 2nd Amendment is too difficult. Therefore, they want to redefine what the 2nd Amendment says.
