I was a Fundamentalist Christian and a bona fide far righty for many years. So yeah I can see their views. That's why I am able to connect to those people and talk to them.
The notion that one can go from right to left is a fallacy. We were all born as little lefties screaming for a tit or bottle. As we were raised, some of us maintained the commie state that we were born in, but some of us were taught judeo Christian values and the values of western civilization. This is what makes us righties. We cannot EVER go back to our animal nature of being lefties, and we can NEVER become uncivilized again. We all still have an inner lefty, but we are civilized and are able to resist doing the bad things that it wants to do.
While righties can never go back, lefties can still go forward any time in their lifetime. Lefties can still become civilized and learn the values of western civilization.
The only explanation of why you believe that you went backwards to being a commie again is that you never stopped being a lefty in the first place. A commie who is surrounded with Republican or conservative family and friends can fit in, but they always feel like something isn't right. He can vote Republican or call himself a conservative, but still have a commie soul.
