It has taken on a life of its own and has been twisted to the breaking point by gun nutters. It is never enough for them and any push back is like pulling teeth. They have become the terrorist at this point and there is no reason to negotiate anymore.
See it from their perspective: every time they've given an inch, grabbers took a mile. If you want to get concessions you're going to need to give some too.
That's not going to happen in the lifetime of anyone who can read this comment.
Because it requires more than a majority of Congress, it also requires 3/4 of the 50 states to vote to ratify it. Only takes 13 states voting NO to prevent it, and there are plenty more red states than that who would never give up our rights so foolishly.
It will never be enough. Look at the responses in this thread and elsewhere. It will never be enough. There is no price too high that it won't happily be paid. There is no regulation small enough that it will be accepted. They have made that exceptionally clear.
There is no negotiation with them. You will never convince them. It doesn't matter if the regulation works or not.
