The reason people cannot or will not be kind to each other is because for one thing it has not been that long since the civil War. My mother’s great uncle fought in the civil War and she actually knew and spoke with him as a child. We have photos. There is still a living person whose father met and spoke with Abraham Lincoln.
There are still a couple of Civil War widows getting veterans’ benefits and about 17 children of Civil War Vets still around. For another thing Sherman’s March and the yankee reconstruction/retribution on the South was so harsh that we still hate the North.
That is why there is such vitriol on the FR threads whenever Robert E Lee or any other Confederate leader is mentioned in a thread.
Currently our country is in another similar cultural war and if something drastic does not happen we will see the regional division happening again.
So no people are not going to be kind to each other about this.
I've spent a few vacations in the South and have seen no evidence anyone hates me for having northern plates. I think you and your few holdouts just like to have something to irrationally hate.
