"I am the only living witness but I must say the truth. Contrary to the opinion of the National Socialists, that the Jews were a highly organized group, the appalling fact was that they had no organization whatsoever. The mass of the Jewish people were taken complete by surprise. They did not know at all what to do; they had no directives or slogans as to how they should act. This is the greatest lie of anti-Semitism because it gives the lie to that old slogan that the Jews are conspiring to dominate the world and that they are so highly organized. In reality, they had no organization of their own at all, not even an information service. If they had had some sort of organization, these people could have been saved by the millions, but instead, they were taken completely by surprise. Never before has a people gone as unsuspectingly to its disaster. Nothing was prepared. Absolutely nothing."
- Erich von dem Bach-Zelewski
Because they're a paper tiger: a bunch of frail and helpless Woody Allen-like people who have no power besides financial manipulation and media propaganda - which is a highly destructive power capable of ruining nations - but once you take that power away, are in no way equipped to deal with the enormous blowback they create and are instantly destroyed. Don't live by the sword if you're not prepared to die by the sword.
What you're describing is also known as collective punishment. Yes, not all of those people are actively plotting to screw over everyone else, but the fact remains that if you REFUSE to police your own kind and let them act like psychopaths constantly trying to drain everyone's wealth through usury and manipulate society with destructive media propaganda, you force the other side into making the Machiavellian choice of, "welp, I can either live as a slave or wipe out the slave masters entirely".
History will repeat once again, because once again they have refused to police their own kind while citing their Talmudic religious texts that claim non-Jews are "goyim cattle" who are below jews and meant to serve them. In case you haven't noticed, Christianity is mostly a benign religion nowadays, while both Judaism and Islam are still outwardly hostile death cults to anyone they come in contact with.
The world is a place with lots of incompatible people, religions, and cultures.
The only incompatibility stems from being afraid of what's different.
Bullshit. Different just means "diversity", which is just a synonym for "less white people" or "white genocide". I notice you aren't walking around in China or Africa amongst the 99.9% Chinese or African population and complaining to them that it's not "diverse" enough. No, uttering propaganda words like that simply means you're an anti-white Marxist. It's honestly amazing white people fell for that propaganda for such a long time, but now it doesn't work anymore and you're just identifying yourself immediately as a hostile enemy combatant by uttering such words.
