Because it always goes that way.
Humans are predictable and often react in the same way.
A murder happens. Usually of an innocent child.
A foreign person (or a person of foreign parents ) did it.
Humans then go and blame (all foreigners) for it.
It doesn't make sense. And it never does. And it's not right
But it has happened so so many times i
over and over in history.
Humans never seem to be able to separate the individual, from the group.
Examples in history:
There was an IRA bomb put in England.
Reaction at the time - hate all the irish. All the irish are responsible.
Another example - The British Invaded ireland.
Reaction- hate all the British. Even if they werent born at the time. Every British person was responsible.
The 911 attacks in America. Carried out by a group of Muslim people.
The Reaction was - hate all the Muslims, every single Muslim in America is responsible.
This recent murder in England- a "foreigner' murders children. Reaction - hate all the foreigners , all foreigners are responsible.
Humans always react in the same way
