A lot more who really liked it.

There were a lot of people in the North called Copperheads that couldn’t give two poops about slavery, believe it or not.

Yes there were. Unfortunately the elites of the South were not and decided on a course of action that resulted in a war they could not win

"There were a lot of people in the South vehemently opposed to slavery, believe it or not."

Of course there were, especially in regions like western Virginia, eastern Tennessee, western North Carolina, northern Alabama, northern Texas & northern Arkansas, not to mention most of Maryland, Delaware, Kentucky & Missouri.

Those people hated slavery, hated slavers and remained loyal to the Union throughout the Civil War.

That's one way you know for sure: the others who declared secession did so to protect their most peculiar institution.
