M14 Shooter and others have made that argument: that the government can take away any right you have as long as they have a court hearing first for due process. In fact, with due process, they can take away the right to due process so from that point on, the government doesn't even need due process to strip the rest of your rights.
According to him, and others on this board, a right stripped is as if it never existed. It's not a violation of a right, not an infringement of the 2nd, not a violation of right to trial, not a violation of right to representation, if the right was stripped by the government. It seems that a stripped right is as if it never were and you can't infringe on a right that never was.
Seriously, M14 Shooter has made that claim multiple times and vociferously defends it. There are no rights that are protected by the Constitution. None. Not even one.
I can post it all again, if you doubt me.
