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)
Sorry, but all Google shows me is that Marx supported abolitionism, not that the abolitionists were fans of Marx. And I've been on enough Google snipe hunts trying to find evidence of yet another lost causer assertion to waste more time on it. You got proof? Post it.
And judging from the rest of your post, I take it that you believe women shouldn't be allowed to vote and that people opposed to slavery should have kept their mouths shut.
