What's up with all the liberals choosing the 2nd over the 10th?
Why can't liberals support federalism?
Because the 10th Amendment has been far too broadly and vaguely worded and has been used to support all sorts of reactionary state policies.
This critique applies to large sections of the Constitution. But "get rid of" is not the same as replacing, rewording, or taking a different interpretation. I don't support the "right to bear arms" at all - and I think that the belief in said right has caused our country and it's people a great deal of harm - so if the question is about eliminating an amendment entirely, the Second Amendment is any easy choice.
Yes, if only we applied to the violent arm of the government too, the fascists you probably condemned in another thread for their brutish savage tactics in Ferguson.
