It's quite simple. According to their fucking religion, the Jew knows that they can lie, steal, and murder. Also can rape children, or whatever else.
If you are nice to them, they will try to do all these things to you.
If you just tell them to fuck off, they will cry in pain and go away.
Do not trust Jews, live long and prosper among your own people.
Also niggers and faggots obviously. And now also pajeets.
