Look, I'm not disagreeing with you that the world would be a better place if we all took care of each other. Yes, it would be swell if people were kind and helpful and wonderful to each other. An idyllic society, with the lion laying down with the lamb would be perfect. Pretty much what we all want. It is, indeed, what many people consider heaven to be. And indeed, we all should daily be striving to be nicer to each other. My sister teaches her kids "Did your action help the situation or hurt the situation". A good question for us all.
However, Mayberry, LHotP and Bonanza did not ever exist. For sake of argument, let's stick with Mayberry. Sure, there were and are small towns that look like that. And yes, people knew each other and helped each other out. They grew their own food, raised chickens and baked from scratch. Good stuff, all of it. At the same time, women were being beat black and blue by their husbands because dinner wasn't on the table fast enough. Children were abused and neglected. Animals were abused and neglected. The sheriff could and did lock people up purely because of the color of their skin. Men and women could be and were killed because of what we now call lifestyle choices. Sure, the people doing the neglecting and abusing and killing raised their own meat and grew a garden. That didn't make life in the past perfect.
My mom's family raised chickens. Her daddy was a raging alcoholic who beat my grandmother. Then they all went to church on Sunday. My daddy was raised on a farm. They had a huge garden and raised chickens and the occasional pig. He also slept in a bed with a herd of other children so they could stay warm on the days they woke up with snow on the bed. In the house. Fuel was expensive and my great-granddaddy saw no need to keep the whole house warm at night. Both parents grew up in a town very much like Mayberry. Did it mean life was perfect? Absolutely not. Did my parents turn out okay? Sure. They are both amazing people and have had a good life. But Mayberry never, ever has existed. It is a set filled with props and actors saying lines that were fed to them. Again, the real world is messy and disagreeable and not anywhere near perfect. It never has been and never will be.
You say you want people to all get along, but what you mean is that you want everyone to play nice with you and not disagree with you. People can have differing opinions about things and it can still be okay. I hate GMOs and would love it if our laws were such that foods were labeled so I had the choice to pick out non-GMO food at the store and seeds at the co-op. But I appreciate that Dennis and others can have different opinions about GMOs. There are many people on here that I disagree with on certain topics. They have different opinions on how to feed themselves, how to raise their poultry, what our government should be like, what their "lifestyle choices" are going to be, and different religious beliefs. Does that mean that they can't play on my threads? Heavens no. At least in America we have the right to express our views on things. If you start a thread you are opening that thread up to differing opinions. Coming back later and saying "Okay, everyone can play but you" is meanspirited. It is very un-Mayberry like, the very thing that you are hoping for.
