I'd be interested in seeing where any Abolitionist acknowledged ever having heard of Karl Marx.
Google is your friend, Bubba. (”abolitionists, Karl Marx”) So is archive.org (That’s where the truth is. Before it became propagandized.)
Betcha didn’t know that feminism (”women’s suffrage”) & “free love” are also rooted in abolitionism. Don’t quote me, because I’ve read a lot & it’s been more than a year, but I believe it was Harriet Beecher Stowe’s bunch (I want to say her brother?) were into bisexuality, too.
These people were professional agitators.
Not kidding. Look this stuff up. It’ll blow you away. Look up John Brown, while you’re at it. Now, there’s a fine specimen of a “moral, upright” man. (Not)
