I am sorry, you're wrong.
Christianity says justice is God's only. So it's unchristian to do justice by yourself.
So violent means are unchristian.
Crusades were unchristian.
A populous groups of holy people who repel wicked people.
Wicked people can't be wise.
Only good people are.
Suuure.
Christianity says that there are no winners or losers in the worldly dimension.
Only when we die, in the otherworldly dimension, there are the blessed and the damned.
I think many missed that memo.
