Oh, I have no doubt they could do it double-quick. Europeans are almost as clever and organized as they are blood-thirsty.
I still see no difference between you calling Europeans blood thirsty and me calling Germans blood thirsty. .
Call me bigot if you will. That's fair enough. But I prejudge no individual based on nation of origin. Just pointing out trends in history and current political reality. For the record, ALL humans are violent, aggressive, blood-thirsty animals. Some have just proven more effective at carrying out the impulse.
Someone being of German origin is no more an indicator that they are racist than someone being racist is in any way a suggestion that they are likely of German origin.
If you run into a creature that happens to be human, you'd better:
1) Be within a nation of laws
2) Be confident you are better equipped to kill them than they you
3) Be able to outrun them
Or have the confidence and courage of faith and goodwill - and hope for the best
But no matter how badly many Europeans may strain to look down their noses at America, history is what it is and they know it.
