Normies, chads and foids all have a sinful mentality and their belief is that that physical appearence matters. No matter how much they reject it, they still act on it. That foid not giving a subhuman a chance because of his looks is sinful behaviour that she refuses to change despite being confronted about it.
James 2:1-5:
My brothers, show no partiality as you hold the faith in our Lord Jesus Christ, the Lord of glory. 2 For if a man wearing a gold ring and fine clothing comes into your assembly, and a poor man in shabby clothing also comes in, 3 and if you pay attention to the one who wears the fine clothing and say, “You sit here in a good place,” while you say to the poor man, “You stand over there,” or, “Sit down at my feet,” 4 have you not then made distinctions among yourselves and become judges with evil thoughts? 5 Listen, my beloved brothers, has not God chosen those who are poor in the world to be rich in faith and heirs of the kingdom, which he has promised to those who love him?
With the mentality that normies, chads and foids have, they are rejecting the word of God by treating people by the way they perceive physical appearance. I'm sure you're already aware what happens to people who despite getting corrected, still refuse to accept the word of God and go by their own way, they are actively in mortal sin. So yes, it's a wrong and evil doing to treat people differently due to their physical appearance. And as for those like muslims, jews and others who reject Christ even after being proven wrong, there is a justification to exterminate them for the greater good. This also applies to heretics and apostates.
