Yes, *HOW* could America have succeeded having based it's culture on it's succession from Britain?
We didn't secede from Britain, if for no other reason than we never joined Great Britain. We fought a revolution, something for which the Founding Fathers understood they could be hanged if they lost.
Southerners, of course, refuse to call their actions a revolution or rebellion because they lost and so seek solace in the notion that it was all somehow unfair. I have no doubt that, had they won, they'd be proudly trumpeting their successful rebellion.
You forgot your /sarc tag. You can’t possibly be foolish enough to believe they’re analogous. Can you?!
