You're just raving now. The scenario you envision isn't possible in this, or any alternate universe.
Can you wrap your head around the the number 1,000,000? That's one million. For perspective, dividing that number by 365 (days) works out to 2,739 years, which is over 700 years before the birth of Christ.
Now try to wrap your head around the number 150,000,000. That's the number of American gun owners, which works out to over 400,000 years, if each person represents a single day.
Are you beginning to get a sense of the scale of what we're talking about?

I’m not suggesting at all that they will be successful. I am saying they will try.
