For start, a Buddhist could never ever do what the article is saying here.
Because the path of the Buddhist is to overcome your feelings, to enlighten yourself from this world.
So they could never ever do those actions what the article is saying.
It's a contradiction.

And what the Japanese did, is what happened in every major war worldwide.
Soldiers rape woman in every war or conflict, it has nothing to do with religion, culture or country.
It has to do with orders from above, who order soldiers to rape woman. That is to destroy the root of the nation, and that is the woman.
Look what happen to Berlin after WW2, not only Russian soldiers attacked woman, also the Allies in Western Germany.
Or how about Vietnam and Cambodia, or here in Europe Yugoslavia or in Iraq.
It's going on in every war situation, and there for it's better not to support a war, or to support a conflict, or to focus on articles who only want to divide people, by placing them in box and label them as Muslims, Christians or Buddhist.

Because the truth is, people are not what they say who they are, they are how they live.
That means if anyone is raping woman, murdering people then they are psychopaths, and not this religion or that religion!
So the only conclusion i can make is, that the article uses disinformation to get money from Christians, who could believe the article.
If they want to save Christians, let them demonstrate to stop those wars who created those situations in the first place.
