Jews are simply a part of the equation. For the chemical reaction that is the observable downfall of western civilization, whities are just as much to blame. You can't have a proper chemical reaction without reactants, those were the circus and the bread. The Jews acted as the catalyst and the resulting product is a civilization that is obsessed with the circus. Such civilization will be increasingly susceptible to the machinations of a ruling class that controls the aforementioned circus.
We can't ignore the proliferation of American pop culture here, parts of which have influenced almost all of the world. For the "leftists", they parse the realities of struggle through the filter of a "manufactured struggle". What do I mean by that. Think of movies and games with antifascist undertones like Harry Potter, Star Wars etc. Those that became the fans of such movies inhabited leftist ideals without even realising it. Those that grew up wanting to fly the X-Wing and shoot down "le evil empire" became the facilitators of modern leftism:
"Military is bad and is only good when saving ugly aliens"
"Patriotism bad"
"Rule of well-kept and well-groomed officers bad"
"Struggle of ugly and brown Aliens good"
Convenient how bankers and war profiteers were never mentioned and the supporters of the Empire were dehumanised as mindless henchman
As you can see, it's all so superficial, exactly how the ruling class aka the Jews had wanted it to be. It didn't take much for them to instill such messages.
And those that became the modern rightoids can have their ideologies traced back to the very same movie. The fans of the Empire.
Most supported it because it looks cooler. Then these very same people parsed the rebels as cringe and ugly. Yes, that's indeed how they should perceive it but that's what the Jews wanted too. They took into account some would support the Empire.
And what did the Jews do ? In a couple of decades, they popularised the sjw cringe compilations and gamergate stuff to get an uber jew like Trump elected, with the help of other uber Jews like Ben Shapiro etc.
It's all good tho, the cringe libtards are owned
