During his War his pin-pal was That “thing” Marx himself..
Those letters are easy to find
That doesn't make him a Marxist any more than writing to my wife makes me a woman.
Please answer the question. Do you know what Marxism means?
There is exactly one letter, written by Marx and congratulating Lincoln on his reelection and for putting an end to slavery. The letter was presented to Ambassador Charles Francis Adams, who wrote a thank you letter back. Lincoln never wrote directly to Marx and in fact there's no evidence that Lincoln ever read the letter, since Adams' thank you letter was written the same day he received the letter from Marx and there was no transatlantic cable operational in January 1865. They were hardly pen pals.
