Well, I have come across many Christians in India who try to criticize Hindu teachings of reincarnation and so on. I felt this may be the prevalent belief in the west as well.
In a way you are right, because in the West there just happen to be quite a few Christians
I have not come across many Christians in the world who try "NOT to criticize" other religions or teachings
Once upon a time, when I was still believing "It must be only Dutch Christians criticizing other religions as per habit"
I skyped with an Argentinian woman and asked her:
"Here in Holland Christians always criticize other religions; I think it's not the same in Argentina, is it?"
"Oh no my dear, it's the same over here, I think it's the same everywhere in the world"
