This^^.
The Crusades were done by people who didn't understand that the way of Christianity isn't a violent, earthly-government one. From https://en.wikipedia.org/wiki/Crusades:
Quote
The Crusades were military campaigns sanctioned by the Catholic Church in the Middle Ages.
Because of this, what can anyone expect?... especially from strictly Roman Catholic countries like Italy and Spain and Portugal?
How about Vietnam, Afghanistan, Iraq and Libya?
Luckily NOT this.
Best regards.
Are those countries Roman Catholic? After all, they didn't take part in the Crusades, did they?
What are you talking about? You need a better translator.
EDIT: No offense, but are you in an insane asylum?
You are doing quite well for a 12-y-o.
