Because you let them talk. I was there raising money in front of 770. Some hood rat screams he's gonna kill all the Jews. Everyone puts their head down and walks. I left the money and the stand and screamed, "come, Jew right here" and he bolted like the rat he was. I grew up around lots of black people in poor neighborhoods. You let them talk to you like a dog, they're gonna feel powerful and treat you like one. You break their ugly faces when they open them in a way and tone you don't appreciate, they scurry back to their burrows. Because of that particular upbringing, I felt the same disrespect towards my people he did, they took the abuse and didn't return it, I had to keep my pride in check after. This isn't a case of love between Jews, Rav Kahane was very adamant it's pride in Hashem to defend your people, no mercy, no forgiveness, no accepting the tiniest slight, even if they say something innocent in a disrespectful tone of voice, you beat respect into them. After they lose a fight to you, they will not see themselves as the king of the hood, they will see themselves as the b***h of the hood and keep their heads down.
It's really quite simple. It's a life where everyone treats you like a dog and tries to abuse you first chance they get. Especially authority figures. The authority figures let you talk, they know they have the power, and laugh at you. Now you've got to prove yourself. As such, they'll want to let that abuse out on others, and Jews are acting like the government aholes they have to deal with by being nice and modest, as is our nature. You show you don't take it, they'll move onto the next victim. Take everything as a death threat, because it is if you do nothing. Retaliate ten times harder if one gets through. Then you can live along them just fine. Get used to being an object of fear, they're afraid of everything, it's a scary life. Mild manners are for each other, run the hood or it runs you over.
I wonder if the Jewish Bible should have been translated at all. There would be fewer theological delusions in the world if Gentiles stayed away from the Jewish Bible.
When does Hashem ever make it easy? At least it's not boring.
