Yes it has, and it's about time some recognize that there is a balance between the rights of individuals and a secure society. Government has both obligations. You don't seem upset over all of the 1st Amendment restrictions that exist.
How does making us more vulnerable to attack make us more "secure"?
Trust me, We're upset. I know that emotions tend to get elevated on these threads, so let's not be silly.
To generalize, we "gun nuts" understand that the best way for wanna-be dictators to get their power fix is to FIRST render the Second Amendment meaningless. Then you will definitely see the "Fairness doctrine" and worse.{Kiss Free Republic good by, also} You will see the end of jury trials, the end of the concept of innocence until proved guilty. When the Second is gone and the law abiding are only armed with pitchforks, why should any redress of grievances be taken seriously?
