Do you want to talk emotions or law? OF COURSE, people are going to feel all kinds of emotions. The Jewish people have those emotions about losing their homeland and being wanderers longing for home for thousands of years.
Emotions are not law. There is no provision in law for violence to obtain a political end.
Please just answer the question this one time.
Even if you watched your oppressors demolish your home and your entire town and were then forced to live as a second class citizen watching your oppressors build their town where yours just stood?
Sure. You want to talk emotions? No problem. You want to talk about legitimizing the use of violence due to emotional reasons of someone stealing your home and demolishing it and your entire town and then forced to live as second class citizens while watching your oppressors build their town where yours just stood?!
Let's talk about that. Let's talk about the City of David. Let's talk about Jerusalem. Let's talk about our Jewish city and our ancient Temple there. Which was destroyed, rebuilt, destroyed again and then usurped by foreigners who built their 'home' on our land and whose building on stolen, holy, sacred ground is now THE globally recognized symbol of Jerusalem and the holy places there.
Let's talk about the destroyed synagogues in Jerusalem, in Gaza, in Judea and Samaria. Some thousands of years old. Let's talk about the 900,000 Jews displaced and forced to flee from their homeland in Israel and from the ME.
Let's talk about Bet Lehem, which is now a "Christian city". And Hebron and the Tombs of the Patriarchs, which is now a "Palestinian city" according to UNESCO.
There's more. Do I need to go on?
The Jewish people have PLENTY to say and feel about stolen land, stolen holy places, stolen sovereignty, oppression, second class citizenship. If you think THAT is the source of international law and if you think THAT legitimizes violence then OWN it.
