" I'm talking about having a chip implanted in your body that will tell anyone with the right equipment, including law enforcement, who you are (and potentially everything else about you) just because you came in range of their scanner."
Well first off, the chip dosen't tell them "everything else about you" - it's an ID that leads them to a data base which may or may not hold "everything else about you".
Just like your driver's license number does now.
... and IF you choose to live where you are forced to have this implanted, you have agreed to it allready.
OMG! You can't possibly be that retarded, can you?
Right. That's a lot like the folks who buy a house out in farm country then try to outlaw the smell of bovine excrement - and telling the farmer that they agreed to the new restriction when he allowed the busybodies to buy their houses.
Congratulations on your leap of illogic.
