They are trying to make a criminal out of me for exercising my rights!
Which would give them a route with which to use government force to disarm or kill me.
Government only has one method of forcing compliance: pain of death. Do not be put off by the softer punishments one might accept in the place of death, but at the compliance end....all governmental force is predicated on the ability to use violence to achieve submission. Rights stand in the way of government justifying use of force. Erosion of a right, even a little bit, allows for more governmental use of violence.
Rights are specified things the government is specifically prevented from using force to limit, prevent, or manipulate. It is not in any of our interests to allow government to erode those rights because the alternative is far worse (totalitarianism).
If Nancy Pelosi pushes a law (and is successful in getting it passed) that leads to governmental use of force that ends in the death of someone exercising a right....she is a killer. No matter that she didn't pull the trigger, she still caused the death of a citizen exercising a right. Period. Pen or sword, same result.
That's no different than what ISIS wants to do to me because I'm a dirty westerner who doesn't follow muslim law.
