Did not intend to rub you wrong or offend, but in my experience I have seen it a bit differently. It has nothing to do with being here first. Sure, I surmise most of them are moving south to get away from something, but I see it over and over when they get here they complain about the way things are and are done here.
For starters, some don't like it that there are no county zoning codes outside of city limits. What this means is no one can make me mow my yard, put the wheels back on the car on blocks in my front yard, or tell me to move my washer & dryer off the front porch.
Some have been offended enough to call the sheriff's office and complain about the Confederate battle flag waving in my neighbor's front yard. They got offended again when they got laughed at.
We had a brew-ha-ha recently when a retired couple from Massachusetts called the law on a couple who whooped their youngun' in Walmart for misbehaving. They didn't seem to understand the concept of corporal punishment.
Had a fellow and his family move down here from Michigan a few years ago. Decided he'd run for school board to get acclimated in the community. Seemed a nice enough guy and got elected, then the first thing he proposed was to remove those dad-gum offensive Ten Commandments from the school house.
Yet another family from Illinois moved to the area and were aghast to discover they had moved to a dry county. Wanted to push a ballot initiative to change it. When he complained to me about it I reminded him we'd been dry since prohibition so it was already dry when they got here.
Now, I'm sure there are some that move south and settle right in and try to adjust to the local culture, but there sure are a lot of whinny ones that bring with them what they're running from. THAT rubs me the wrong way.
