This is certainly worth saying.
But it makes me sad that so many people don’t know history. The movement of peoples is a big deal and it is a constant throughout history.
Invading armies tend to kill the men and rape the women so that the next generation is a bit less native. Look at Europe today. Look at the rapes in Scandinavia. The old pattern repeats.
Sometimes the story is literally about an invading army. The Ottomans at Vienna in 1683 is right on target. But sometimes it’s a lot more than an army. Part of why the Roman Empire “fell” is because masses of people moved in, speaking their own language, following their own ways, ignoring Roman law, and just refusing to assimilate. Look at the US today. Illegal immigrants leave their homeland, come here, and try to change us so that we can be just like their homeland. The old pattern repeats.
People are ignorant of history, and in part I think this is deliberate. The Powers That Be would prefer that you learn these lessons all over again — right up close and personal.
