It has taken many years and millions of lives to discredit and undermine Marxists and Freud is almost gone...it's going to take the same commitment to get rid of the dangerous old fool Darwin. Some people are still firmly stuck in the 19th and 19th century.
Marx was an ideologue with little respect for facts (he published outdated statistical tables in later editions of Das Kapital because newer tables contained data that undermined his economic views); Freud was a physician who spun imaginative theories out of the dreams and fantasies of repressed Viennese Hausfraus.
Darwin, on the other hand, was a hard-headed, fact-checking, observation-collecting machine, a man who theorized only after long years of work and reflection.
Darwin was a scientist; Marx and Freud were patzers.
Well it's incredibly easy to criticize Marx & Freud now that they have been largely discredited and act as if it's oh-so-obvious that they were phonies, but at the zenith of their movements, every respectable member of the fields of economics and psychotherapy, respectively, consider them to be almost beyond criticism, their theories not just theories, but the most compelling organized understandings of their subject matters.
In fact, to have criticized them at one time is to have committed professional suicide. Marx and Freud's disciples would have marshalled impressive defenses of their Prophets during the heady days of their dominance.
Darwin is still in his heyday. But I'm sure it's oh-so-different in this case. Yes, that's right, it's different with Darwin..
Your pet Darwin was a fraud! Here is love note to marx from your pet:
Dear Sir:
I thank you for the honour which you have done me by sending me your great work on Capital; & I heartily wish that I was more worthy to receive it, by understanding more of the deep and important subject of political Economy. Though our studies have been so different, I believe that we both earnestly desire the extension of Knowledge, & that this is in the long run sure to add to the happiness of Mankind.
I remain, Dear Sir
Yours faithfully,
Charles Darwin
