I've heard of so much evil going on in Europe. The only good thing that'll come from this is that Europeans will wise up and learn that not to brush all Muslims as saints and will learn that it's not racist to say CERTIAN, INDIVIDUAL muslim immigrants are utterly evil.
On the flip side... on the camp that already see's this. There are those who outright take racist stances. Just like the mindless people who don't care about the dangers that some refugees if not all have caused. You can't be racist about it.
It is actually logically possible for an entire group of people to be a murderer. However, it's HOW you pin point the CAUSE. No, it's not because of skin color.. it may be about ideology like a certain Muslim sect or belief system. However, its not caused by skin color. You can say all middle eastern men are thieves BECAUSE each individual believes certain thievery is okay.
It's a matter of telling the difference between physical things (like skin color) and beliefs/values/attitudes.
G-d said that mankind looks at the outward appearance but he looks at the heart.
1 Samuel 16:7
But the LORD said to Samuel, "Do not consider his appearance or his height, for I have rejected him. The LORD does not look at the things people look at. People look at the outward appearance, but the LORD looks at the heart."
