Did you know that a lot of Palestinians have blue eyes? Some of them blew east, some of them blew West.
That sounds a little odd. I don't get the joke, what's the punch line?
Ok.. No problem. Basically, I'm saying Palestinian means terrorist and they are terrorist sympathizers or wanna be terrorists.
You shouldn't make blanket statements like that. They're hurtful and make incorrect assumptions about groups of people.
Eh, it's just a joke.
It being a joke doesn't automatically make it okay. Not all Palestinians are like that, and are rather very kind and hospitable people. They would feel better if you focused more on their good side than anything else.
