You are contradicting your own article:
Marx was baptized a Lutheran in 1824, attended a Lutheran elementary school, received praise for his earnest essays on moral and religious topics, and was judged by his teachers moderately proficient in theology (his first written work was on the love of Christ)8-10 until he encountered Darwins writings and ideas...
Do you have any documented proof that during his Lutheran education and upbringing, he studied the obscure Greek philosophers like Anaximander or Empedocles or the Chinese philosopher Zhuangzi or any other of the very obscure philosophers who pondered this idea? Did he attend the Linnean Society of London as a youth, one of the only modern groups studying the possibility of some sort of evolution at the time?
It seems you are so obsessed with demonizing this a-moral and a-political issue, that you are now just willing to make stuff up.
“Marx wrote tirelessly until he died, producing hundreds of books, monographs and articles.”
—How many sentences, total, did Marx write which involved Darwin? Three? That’s all I can currently find... in two separate statements, both in private letters (of which there are many hundreds, consisting of thousands of pages). Was there anything public?
Some “seizing”.
