It is not worth getting into the gutter and debating pond scum. The good thing is that you are a very small minority on FR. However, if it makes you feel better, you can babble to yourself in the mirror.
Actually that's not true. Most Americans got over the WBTS decades, even generations ago. The same is true for FReepers. To them the struggles and the animosities are largely ancient history. In fact, the tiny minority of FReepers that express such venomous hostility and antipathy toward their fellow FReepers when it comes to The Great Unpleasantness is what drew me to these threads in the first place. In all of my travels I had never before encountered the lost causers.
That is also why I find it so amusing when I see FReepers argue in a fashion identical to liberals - the use of logical fallacies and especially the rich employment of ad homs - when defending what they (mis)perceive as slights or insults.
I won't deny that there is a cottage industry in the south which aims to perpetuate the old feuds, but go most places in this nation and mention the Civil War and you're more than likely going to encounter a blank stare. Most people just don't care.
