Why were people in the north angry about the emancipation proclamation

Lol dude, they weren't angry about it at all. It was the South who were a bunch of babies about it. The Emancipation Proclamation said that all slaves were free, and so many Northerners wanted slavery OUT, while people in the South resisted. So people in the South instead were angry about it because they didn't want to be considered equals with black people. They wanted to continue owning black people, and couldn't go on with their lives knowing that their slaves weren't their slaves anymore.
