You talk about this as though it happened 5 years ago. All of this happened hundreds of years ago. Both the perpetrators and the victims died a long time ago.

What does any of this have to do with the debate around immigration today? They're completely separate topics.

It's completely irrelevant.

Imagine a young Japanese boy moves to China and starts getting bullied in a Chinese school.

The teacher tells him: "Oh, so you don't like being bullied? Well do you think the Chinese people liked being slaughtered by your ancestors in WW2?"

What relevance does that have to the young Japanese boy? None.
