You must be talking to Gen. U. S. Grant. Slavery was legal both in the north and the South. The South did not own a single slave ship, the north did.
Either that, or you're sharing with us your last conversation with your IRS agent.
Interesting isn't it that those who defend the north's attack are also the first to mock the slaves that they supposedly wanted to free. Keep it up, the arguments are falling through, more and more documentation is coming out about Black Confederates (the d@mned monuments all throughout the South to them aren't there for giggles) and the true causes of the War are being told for the first time in 136 years.
Keep preaching your 'it was all about slavery' while you can. We are finally seeing the fruits of lincoln's EMPIRE. Keep up your praise of lincoln and 50 years from now you'll know who to thank for the situation this country will be in.
