Subject: Re: Hamas "TERRORISTS!"
I think the "slavery was good for them" is a more recent rationalization (e.g. "if their ancestors weren't enslaved, they wouldn't now live in the USofA!").

There is that.

But the southern secessionists most definitely believed that slavery was good for all concerned. They said it over and over again. This is all well documented. So it is not just a recent rationalization.
