You put blame on the Protestant Reformation/Protestant Thinkers for people like Rousseau, Hegel, and Marx, who came later, even though such thinkers explicitly rejected Christianity.
If you're going to blame people for the ideology of someone else who has rejected the core of said people's ideology, then by logical extension, the Catholic Church and its thinkers are responsible for the Protestant Reformation, and thus for Rousseau, Hegel, etc.
Oh, it gets worse.
I think monotheism may well be the worst thing to happen in human history.
I mean...
Judaism was intolerant from the beginning, hence their problems with Rome. Early Christianity was better, but the fact that the Scripture was written down quite late meant that you had
dozens of still-extremely-intolerant sects that were considering each other heretics. So what happened was that Constantine adopted Christianity for political reasons. But Christianity also spread outside the Empire - and much like Romans saw Zoroastrianism as Persian propaganda, so did Persians see Christianity as Roman propaganda.
This turned Roman-Persian wars into far worse religious conflicts. Even worse, the incense trade was shut down because Christians did not use the incense (oh irony!). This basically devastated Arab economy, which led to a certain murderous psychopathic cretin to create his own religion that was based on a mix of Judaism, Christianity and InsanityTM. Said religion then pushed outwards, eventually conquering into the central Asia. And this cut off trade between Europe and China, so Europe had to look for another way to get silk, spices and drugs.
Enter
Orlumbus Columbus. He came, he went and he lost his way to India, ending up in America instead. There were natives. There was also a lot of gold. So Europeans came, they conkered and then they divided. And then the colonial wars started. Most of them quite irrelevant for our story here, except for one - the Seven Years War. You see, that war was
bloody expensive. And France got a little bit spent. Then taxation without lubrication led to 13 colonies deciding to go their own way... so France got a little more spent supporting the rebels, basically winning the war for them. Which rebels' descendants, of course, prefer
not to remember (Spain also lent a hand to Americans, but literally
nobody remembers that, so eh) and instead believe that their God-given might of throwing teabags into sea, slavery and genociding natives was solely responsible for their victory.
But yeah, France got spent. And Americans had those crazy ideas which infected idiots in Europe, and moreover, had shown that a revolution could be successfull. And there was much rejoicing. So the idiots decided to rebel. And so they rebelled. And chopped off the King's head. And there was much rejoicing.
Other kings however, rather unsurprisingly, did not like this. So they invaded France. And got thrown out. Now France decided to do their own invading, and conquered the continent, infecting most of it with their own brand of InsanityTM. But MidgetInChief was eventually defeated by his stomach problems and got sent to a certain remote vacation resort. And there was much rejoicing.
Hooray! Or not. Because InsanityFrancoise did not, in fact, disappear. It was around. And then it reappeared in the Fun and Parties of 1848. Fun was stopped in 1849, but insanity remained. And worse, Germany decided to get reunited for the first time ever, all organized by the Grand Moustache Man. France didn't like that, and France attacked. France got spanked. And then France did what it does the best after spanking - it birthed a new form of insanity. Enter the Paris Circus.
Circus was not very successful, but it gave new inspiration to clowns Europe-wide. Among the clowns was a certain basement dweller with awesome beard and chronical lobotomy. BeardMan created a new ideology of NoWorkAllProfit, which lazy clowns all over Europe accepted hoping that their new LordSaviorAndMessiah will allow them to share in the spoils. But for the longest time, said NWAP (also known as Socialism, a.k.a. LazyJustice) ideology was not very widely accepted.
Then the Third Global Colonial Throwdown (also known as the First World War, for reasons as of yet unexplained) happened. And Germany got wrecked. So did Russia. Lazy Bearded Men Association decided to implement their Communism ideology. They succeeded in Russia but failed in Germany. Nevertheless, success in Russia as well as attempt in Germany created fear that the LazyBeardedMen might try again. This then led to the Inferior Moustache Man deciding to get rid of the Lazy Bearded Men in favor of his own brand of NWAP. He succeeded, but NWAP still needed other people's wealth to survive.
This meant that the Inferior Moustache Man had to invade other countries for his ideology to live long and prosper. Austria got Anschlussed, as did Czechoslovakia, and then the Inferior Moustache Man and the Progressive Moustache Man entered alliance, dividing Poland for 923492834th time. A bunch of other stuff happened, Inferior Moustache Man decided to give himself premature burial, and Progressive Moustache Man took over half Europe. But it didn't stop there, as the Lazy Bearded Men Association infiltrated indoctrination facilities all over the West, and now we are where we are.
Something we can all agree on for a change, I'd think.
At this rate, we are NEVER exploring space. Civilization will die long before that happens.
