No we are not.
...There is no issue at play in America today which comes close to duplicating the matter of slavery which tore the Union apart a century and a half ago ...really?
How about the excessive taxation and domination of the federal government and the states too? So bad now that many pensions and wages of state and federal employees are close to double of those in the private sector. We are litterally slaves to a partial socialist system and that is similar to the slavery issue back before the civil war. Enter into the mix the murder of millions of unborn babies as promoted by the feds, and you have a an even more volatile and split nation today. When we do not own our own wages and can be put in jail for not paying that tribute, and our homes can be taken away from us for not paying a huge property tax which supports a socialist school system...sorry, we have already lost our nation and it is going to have to be rewon.
No we are not.
