“Racist” is what they call you when you aren’t willing to stand by and permit them to destroy your nation, your language, your faith, and your culture without resistance. All the blathering about “hate”, “equality”, “diversity”, and “civil rights” is nothing more than rhetoric intended to emotionally manipulate you into refraining from perpetuating your own kind.
As for the idea that “racism is a sin”, that is pure satanic inversion. Any “sin” invented in 1902 is obviously a fake and man-made one.
