"Israel is the aggressor"
I would say it is an aggressor, but not the only aggressor.
The Gaza rockets were not in "retaliation" but in hate.
They were aimed at ordinary Jews and their children, not soldiers or "Zionists."

Every issue here, beyond the UN membership the thread was supposed to be about, was raised by you and you put only the Palestinian case.

An open minded, unprejudiced person would welcome the case for the other side being put.
But not you.
It makes you angry to be asked to justify a claim, or to show that it is disputed.
If anyone challenges any claim, you call them by vile, ugly names, and you denigrate their personal character.
In my opinion, that makes you something less than a decent human being.

But, I accept that there are two sides to every argument.
