I'm being honest. Willing to bet you'd never heard of it before the past 24 hours either if you were being honest.
35+ years ago in Germany as old-timers were stressing about getting replaced by Turks and their dastardly-colored head scarves.
And yes, I have heard the same sh!t here too for many, many years - that whites will be replaced by members of other races, not to mention racial mixing. That's been going here in the US for many decades. After all, don't you recall all the Jim Crow era laws about interracial marriage?
Ironically, this fear of the whites becoming a minority are from those same people who will have one hell of a hard time doing any sort of procreation to advance their cause. It might be from the lack of testosterone, hence the excessive gun-love and more drastic testicle-tanning cures - the Tucker Trifecta.
I do understand why it might be under your radar as everyone you know and revere is orange.
