What a joke, here is what really happened up there:
From the time of Lincoln's election in 1860, the Democratic Party had warned New York's Irish and German residents to prepare for the emancipation of slaves and the resultant labor competition when southern blacks would supposedly flee north. To these New Yorkers, the Emancipation Proclamation was confirmation of their worst fears. In March 1863, fuel was added to the fire in the form of a stricter federal draft law. All male citizens between twenty and thirty-five and all unmarried men between thirty-five and forty-five years of age were subject to military duty. The federal government entered all eligible men into a lottery. Those who could afford to hire a substitute or pay the government three hundred dollars might avoid enlistment. Blacks, who were not considered citizens, were exempt from the draft.
In the month preceding the July 1863 lottery, in a pattern similar to the 1834 anti-abolition riots, antiwar newspaper editors published inflammatory attacks on the draft law aimed at inciting the white working class. They criticized the federal government's intrusion into local affairs on behalf of the "nigger war." Democratic Party leaders raised the specter of a New York deluged with southern blacks in the aftermath of the Emancipation Proclamation. White workers compared their value unfavorably to that of southern slaves, stating that "[we] are sold for $300 [the price of exemption from war service] whilst they pay $1000 for negroes." In the midst of war-time economic distress, they believed that their political leverage and economic status was rapidly declining as blacks appeared to be gaining power. On Saturday, July 11, 1863, the first lottery of the conscription law was held. For twenty-four hours the city remained quiet. On Monday, July 13, 1863, between 6 and 7 A.M., the five days of mayhem and bloodshed that would be known as the Civil War Draft Riots began.
You might want to do a little research before you make an asinine statement.
If I do very little research then I'd be a Confederate supporter. I'm not saying that from the Northern side the war was fought to end slavery. It was fought, as Lincoln said time and again, to preserve the Union. Slavery was the motivation for the Southern side not the Northern one.
