I think that people have a right to change their mind about something. We often make a choice based upon the information we have at the time. Well, when we know more or new facts are revealed, then it could sway our previous thought process into another direction.
I used to think that guns were bad, bad, bad. But, when Hurricane Katrina blew threw Louisiana, the cold hard facts of the matter were that our government was not there to protect the people who ended up in a state of chaos to fend for themselves. That scared the crap out of me and snapped me into reality that if such an event happens again, I only have myself to depend upon to keep my family and my emergency supplies safe. So, I learned how to shoot, clean and store a gun when I qualified for a permit to carry a firearm.
So, I did a complete turn around on my previous view on guns.
People have the right to change their minds. The problem that I have with politicians is that they make campaign promises to get elected and then do not follow through once they are in office. That is a whole other story of manipulating the voters.
