Too late for the gun issue at that level. The precedent has been set and a new court won't overturn it. Besides the conservative majority will continue to dominate for the next decade.
I rubbed it in to all my liberal acquaintances 7.5 years ago that when Bush was elected that the most important thing he would accomplish is to swing the court to the right side of issues. It really PO’d them and to this day I remind them every chance I get. This decision is defiantly going to give me some more liberal-socialist smashing ammunition. I will not miss a chance to remind them of their socialist failure to disarm our free society.
And you can tell them that thusly, since the Bill of Rights has now been upheld the defense of liberty is now protected and all subsequent INDIVIDUAL rights.
Their COLLECTIVE will never be able to crush us. Not without a fight.
Tell them calmly and politely and then watch the reaction.
