There is a strain of Christianity called Anabaptist that are pacifist, and do not believe in using violence or coersion.

And Quakers, as well as some historical sect that no longer exist, as well as a number of non-christian eastern religions. But I think that the grandparent's point is fair: most religious and non-religious worldviews allow at least for violence in self and national defense.

... And have the freedom to practice their religion because there are people willing to defend their right to do so, on their behalf.

Not true. They practiced it when they were being slaughtered, too.

"I don't think there is any religion/ideology that discourage things like "defending property and people".

Pacifism?

Thanks. Though I need to look it up whether it really teaches to not defend one's right and how it works in reality.

What about "turn the other cheek", "love your enemy" and stuff like that?
